Use `drizzle-kit push` to sync schema to DB. -- `DISTINCT ON` is supported natively via `db.selectDistinctOn()`. Do not use `db.execute(sql\`...\`)` for this. -- Use explicit column projections in `.select({ ... })` instead of `.select()` (which fetches all columns). -- BigInt columns use `{ mode: "bigint" }` and return native `bigint` values from queries. -- Upserts use `.onConflictDoUpdate()` or `.onConflictDoNothing()`. - -## BigInt Handling - -- Tracker upload/download/buffer values are stored as `bigint` in the database. -- Always wrap BigInt conversions in try/catch when processing external data. -- `Number.MAX_SAFE_INTEGER` is ~9 PiB. Daily deltas will never approach this. Do not over-engineer BigInt→Number conversions for percentage calculations on daily deltas. -- Serialize bigints as `.toString()` in API responses (JSON cannot represent BigInt). - -## Timezone - -- All date strings for checkpoint tables and daily comparisons use `localDateStr()` from `src/lib/formatters.ts`, which respects the `TZ` environment variable. -- Do NOT use `.toISOString().slice(0, 10)` for checkpoint dates — that returns UTC, not the user's configured timezone. -- When `TZ` is not set, `localDateStr()` falls back to UTC (same behavior as `toISOString`). - -## Error Handling - -- All catch blocks must either log the error (`log.warn`, `log.error` from `@/lib/logger`) or re-throw. Empty catch blocks trigger the security audit. -- Use `log` from `@/lib/logger` (pino), not `console.log` / `console.error`. -- Decryption errors (stale session keys) should return HTTP 401, not 422 or 500. Use `isDecryptionError()` from `@/lib/error-utils`. -- Scheduler and poll operations wrap checkpoint writes in try/catch so failures don't break the poll cycle. - -## API Routes - -- Every route handler must call `authenticate()` from `@/lib/api-helpers` and check the result before proceeding. -- Use `NextResponse.json()` for responses. -- Sensitive data (encrypted tokens, password hashes, encryption salts) must never appear in API responses. Column projections exclude them structurally. - -## Authentication - -Single-user app with master password auth. No third-party providers. - -- **Three-layer defense in depth:** `proxy.ts` (cookie presence check) → `getSession()` (JWE decrypt) → route handler (`authenticate()` + `decodeKey()`) -- **Session:** JWE (encrypted JWT via `EncryptJWT`, not `SignJWT`), stored in `tt_session` httpOnly/secure/sameSite=strict cookie. Contains `{ ek: encryptionKeyHex }`. -- **Key derivation:** master password → `scrypt(password, salt, 32)` → AES-256-GCM key. This key decrypts all API tokens in the DB. -- **JWE key:** derived from `SESSION_SECRET` env via HKDF-SHA256 with domain-separated info labels. -- **Sliding session refresh:** `proxy.ts` re-sets cookie expiry on every request without decrypting the JWE. -- **Lockout:** atomic SQL counter (`failedLoginAttempts + 1`), configurable threshold, returns 429 with Retry-After. Both login and TOTP verify paths increment. -- **TOTP 2FA:** optional, uses `otpauth` library. Backup codes are hex `XXXX-XXXX`, compared with `timingSafeEqual`. -- **Stale sessions:** when the encryption key doesn't match (i.e., password changed), AES-GCM auth tag fails. `isDecryptionError()` catches this → return 401, not 422/500. -- **Key zeroing:** `stopScheduler()` zero-fills the key buffer on logout. -- **Public routes:** defined in `proxy.ts` as `PUBLIC_EXACT` and `PUBLIC_PREFIX` arrays. All other routes require the cookie. - -Route handler pattern: - -```ts -const auth = await authenticate() -if (auth instanceof NextResponse) return auth // 401 -const key = decodeKey(auth) // Buffer -// use key to decrypt DB fields -``` - -## Security (CI Audit) - -- A static security audit runs in CI (`scripts/security-audit.ts`). It checks for: missing auth on routes, hardcoded secrets, bare catch blocks, console.log in routes, raw SQL in routes, unvalidated JSON parse, unsafe redirects, missing fetch timeouts, and more. -- Suppress findings with `// security-audit-ignore: ` on the line above. A bare suppression without a reason is itself a critical failure. -- URL inputs are validated against SSRF via `isUnsafeNetworkHost()` in `src/lib/network.ts`. - -## Component Patterns - -- Component anatomy: internal sub-components are unexported functions within the file. Single public export at the bottom. Types exported with `export type { ... }`. -- Use React 19's ref-as-prop pattern (direct `ref` prop), not `forwardRef`. -- SVG path calculations with floating-point geometry should round to 2 decimal places for SSR hydration safety. - -## HMR Safety - -All module-level singletons (cron tasks, DB client, qBT SID cache) must be stored on `globalThis` to survive webpack HMR reloads in development. Without this, hot-reloads orphan the old instance while creating a new one. - -## Testing - -- Framework: Vitest. -- Test mocks must match real API response shapes. Do not add fields (i.e., `isPrivate: true`) that the real API does not return — this masks bugs. -- Do not add test-only methods to production classes. Put test utilities in test files. - -## Code Organization - -- Page files (`page.tsx`) should be thin wrappers — mostly orchestration and render logic. Extract business logic, UI sections, and data fetching into components and hooks. -- Repeated code should be extracted to helper functions or reusable components. Do not duplicate logic across files. -- Centralized constants belong in `src/lib/constants.ts`. Avoid magic strings and magic numbers scattered throughout the codebase. - -## SSR / Hydration - -- NEVER read `localStorage` in `useState` initializers — causes hydration mismatch. Initialize with a server-safe default, then hydrate in `useEffect`. - -## Adapter Pattern - -- Tracker platforms use an adapter pattern: `TrackerAdapter` interface with `getAdapter()` factory. UNIT3D, Gazelle, and GGn are implemented. Adding a new platform means adding a new adapter file in `src/lib/adapters/`, not modifying existing ones. - -## Precision Concerns - -- Daily upload/download deltas are computed as BigInt subtraction. Converting daily deltas to Number for percentage calculations is safe — `Number.MAX_SAFE_INTEGER` (~9 PiB) vastly exceeds any realistic daily transfer. Do not over-engineer BigInt arithmetic for percentage computations on daily deltas. - -## External HTTP Requests - -- All `fetch()` calls must include a timeout: `fetch(url, { signal: AbortSignal.timeout(15_000) })`. This is a CI-blocking security audit check. -- URLs from user input must be validated with `validateHttpUrl()` before use in `fetch()`. -- Error messages must not contain full URLs (which may include API tokens). Use `sanitizeNetworkError()`. - -## Validation - -- Use centralized helpers from `src/lib/api-helpers.ts`: `authenticate()`, `parseJsonBody()`, `parseRouteId()`, `validateHttpUrl()`, `validateHexColor()`, `validatePort()`, `validateJoinedAt()`. -- All validators return `NextResponse | null` — check with `if (err) return err`. -- String inputs: check type, trim, enforce length limits (i.e., name <= 100 chars, URL <= 500 chars). - -## Encryption - -- AES-256-GCM with random 12-byte IV. Format: `base64(iv + authTag + ciphertext)`. -- Key derivation: `scrypt(password, salt, 32, { N: 16384, r: 8, p: 1 })`. -- Use `encrypt()`/`decrypt()` from `src/lib/crypto.ts`. Keys are always `Buffer`. -- Encryption keys are zeroed in memory on logout via `stopScheduler()`. - -## Accessibility - -- `useId()` for stable label/input ID association in form controls. -- `aria-invalid` and `aria-describedby` on inputs with errors. -- `aria-hidden="true"` on decorative icons/SVGs. -- `aria-label` on icon-only buttons. - -## Things NOT to Do - -- Do not use ESLint. It has been deprecated for this project. -- Do not use `npm` or `yarn` — `pnpm` only. -- Do not create raw SQL migration files. Use `drizzle-kit push`. -- Do not use `.toISOString().slice(0, 10)` for checkpoint/daily dates — use `localDateStr()`. -- Do not pass unknown props through to DOM elements via `{...rest}` spreads without filtering component-only props first. -- Do not use dynamic code execution or inject raw HTML into the DOM. See `scripts/security-audit.ts` for the full list of banned functions. -- Do not use `===` for secret comparisons — use `timingSafeEqual`. -- Do not use `Number()` or `parseInt()` directly on BigInt database columns. -- Do not commit `.env` files. -- Do not use `JSON.parse()` without a try/catch wrapper. -- Do not use `console.log` in API routes — use the `log` instance from `@/lib/logger`. -- Do not use `db.execute()` in API routes (raw SQL is banned except for the health check `SELECT 1`). diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml deleted file mode 100644 index 75ba6b62..00000000 --- a/.github/workflows/ci.yml +++ /dev/null @@ -1,38 +0,0 @@ -name: CI -

This is fundamentally incompatible with the aim of -protecting users' freedom to change the software. The systematic -pattern of such abuse occurs in the area of products for individuals to -use, which is precisely where it is most unacceptable. Therefore, we -have designed this version of the GPL to prohibit the practice for those -products. If such problems arise substantially in other domains, we -stand ready to extend this provision to those domains in future versions -of the GPL, as needed to protect the freedom of users. - - Finally, every program is threatened constantly by software patents. -States should not allow patents to restrict development and use of -software on general-purpose computers, but in those that do, we wish to -avoid the special danger that patents applied to a free program could -make it effectively proprietary. To prevent this, the GPL assures that -patents cannot be used to render the program non-free. - - The precise terms and conditions for copying, distribution and -modification follow. - - TERMS AND CONDITIONS - - 0. Definitions. - - "This License" refers to version 3 of the GNU General Public License. - - "Copyright" also means copyright-like laws that apply to other kinds of -works, such as semiconductor masks. - - "The Program" refers to any copyrightable work licensed under this -License. Each licensee is addressed as "you". "Licensees" and -"recipients" may be individuals or organizations. - - To "modify" a work means to copy from or adapt all or part of the work -in a fashion requiring copyright permission, other than the making of an -exact copy. The resulting work is called a "modified version" of the -earlier work or a work "based on" the earlier work. - - A "covered work" means either the unmodified Program or a work based -on the Program. - - To "propagate" a work means to do anything with it that, without -permission, would make you directly or secondarily liable for -infringement under applicable copyright law, except executing it on a -computer or modifying a private copy. Propagation includes copying, -distribution (with or without modification), making available to the -public, and in some countries other activities as well. - - To "convey" a work means any kind of propagation that enables other -parties to make or receive copies. Mere interaction with a user through -a computer network, with no transfer of a copy, is not conveying. - - An interactive user interface displays "Appropriate Legal Notices" -to the extent that it includes a convenient and prominently visible -feature that (1) displays an appropriate copyright notice, and (2) -tells the user that there is no warranty for the work (except to the -extent that warranties are provided), that licensees may convey the -work under this License, and how to view a copy of this License. If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - - 1. Source Code. - - The "source code" for a work means the preferred form of the work -for making modifications to it. "Object code" means any non-source -form of a work. - - A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - - The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - - The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work. For example, Corresponding Source -includes interface definition files associated with source files for -the work, and the source code for shared libraries and dynamically -linked subprograms that the work is specifically designed to require, -such as by intimate data communication or control flow between those -subprograms and other parts of the work. - - The Corresponding Source need not include anything that users -can regenerate automatically from other parts of the Corresponding -Source. - - The Corresponding Source for a work in source code form is that -same work. - - 2. Basic Permissions. - - All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - - You may make, run and propagate covered works that you do not -convey, without conditions so long as your license otherwise remains -in force. You may convey covered works to others for the sole purpose -of having them make modifications exclusively for you, or provide you -with facilities for running those works, provided that you comply with -the terms of this License in conveying all material for which you do -not control copyright. Those thus making or running the covered works -for you must do so exclusively on your behalf, under your direction -and control, on terms that prohibit them from making any copies of -your copyrighted material outside their relationship with you. - - Conveying under any other circumstances is permitted solely under -the conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - - When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such circumvention -is effected by exercising rights under this License with respect to -the covered work, and you disclaim any intention to limit operation or -modification of the work as a means of enforcing, against the work's -users, your or third parties' legal rights to forbid circumvention of -technological measures. - - 4. Conveying Verbatim Copies. - - You may convey verbatim copies of the Program's source code as you -receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - - You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - - 5. Conveying Modified Source Versions. - - You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these conditions: - - a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. - - b) The work must carry prominent notices stating that it is - released under this License and any conditions added under section - 7. This requirement modifies the requirement in section 4 to - "keep intact all notices". - - c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. - - d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - - A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - - 6. Conveying Non-Source Forms. - - You may convey a covered work in object code form under the terms -of sections 4 and 5, provided that you also convey the -machine-readable Corresponding Source under the terms of this License, -in one of these ways: - - a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. - - b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the - Corresponding Source from a network server at no charge. - - c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. - - d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. - - e) Convey the object code using peer-to-peer transmission, provided - you inform other peers where the object code and Corresponding - Source of the work are being offered to the general public at no - charge under subsection 6d. - - A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - - A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, family, -or household purposes, or (2) anything designed or sold for incorporation -into a dwelling. In determining whether a product is a consumer product, -doubtful cases shall be resolved in favor of coverage. For a particular -product received by a particular user, "normally used" refers to a -typical or common use of that class of product, regardless of the status -of the particular user or of the way in which the particular user -actually uses, or expects or is expected to use, the product. A product -is a consumer product regardless of whether the product has substantial -commercial, industrial or non-consumer uses, unless such uses represent -the only significant mode of use of the product. - - "Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to install -and execute modified versions of a covered work in that User Product from -a modified version of its Corresponding Source. The information must -suffice to ensure that the continued functioning of the modified object -code is in no case prevented or interfered with solely because -modification has been made. - - If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - - The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or updates -for a work that has been modified or installed by the recipient, or for -the User Product in which it has been modified or installed. Access to a -network may be denied when the modification itself materially and -adversely affects the operation of the network or violates the rules and -protocols for communication across the network. - - Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - - 7. Additional Terms. - - "Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - - When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - - Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders of -that material) supplement the terms of this License with terms: - - a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or - - b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or - - c) Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - - d) Limiting the use for publicity purposes of names of licensors or - authors of the material; or - - e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions of - it) with contractual assumptions of liability to the recipient, for - any liability that these contractual assumptions directly impose on - those licensors and authors. - - All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - - If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - - Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; -the above requirements apply either way. - - 8. Termination. - - You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - - However, if you cease all violation of this License, then your -license from a particular copyright holder is reinstated (a) -provisionally, unless and until the copyright holder explicitly and -finally terminates your license, and (b) permanently, if the copyright -holder fails to notify you of the violation by some reasonable means -prior to 60 days after the cessation. - - Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - - Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - - 9. Acceptance Not Required for Having Copies. - - You are not required to accept this License in order to receive or -run a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - - 10. Automatic Licensing of Downstream Recipients. - - Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - - An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - - You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - - 11. Patents. - - A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - - A contributor's "essential patent claims" are all patent claims -owned or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - - Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - - In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - - If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - - If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - - A patent license is "discriminatory" if it does not include within -the scope of its coverage, prohibits the exercise of, or is -conditioned on the non-exercise of one or more of the rights that are -specifically granted under this License. You may not convey a covered -work if you are a party to an arrangement with a third party that is -in the business of distributing software, under which you make payment -to the third party based on the extent of your activity of conveying -the work, and under which the third party grants, to any of the -parties who would receive the covered work from you, a discriminatory -patent license (a) in connection with copies of the covered work -conveyed by you (or copies made from those copies), or (b) primarily -for and in connection with specific products or compilations that -contain the covered work, unless you entered into that arrangement, -or that patent license was granted, prior to 28 March 2007. - - Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - - 12. No Surrender of Others' Freedom. - - If conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot convey a -covered work so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you may -not convey it at all. For example, if you agree to terms that obligate you -to collect a royalty for further conveying from those to whom you convey -the Program, the only way you could satisfy both those terms and this -License would be to refrain entirely from conveying the Program. - - 13. Use with the GNU Affero General Public License. - - Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU Affero General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the special requirements of the GNU Affero General Public License, -section 13, concerning interaction through a network will apply to the -combination as such. - - 14. Revised Versions of this License. - - The Free Software Foundation may publish revised and/or new versions of -the GNU General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - - Each version is given a distinguishing version number. If the -Program specifies that a certain numbered version of the GNU General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU General Public License, you may choose any version ever published -by the Free Software Foundation. - - If the Program specifies that a proxy can decide which future -versions of the GNU General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - - Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - - 15. Disclaimer of Warranty. - - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY -APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT -HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY -OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, -THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM -IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF -ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. Limitation of Liability. - - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS -THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY -GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE -USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF -DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD -PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), -EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF -SUCH DAMAGES. - - 17. Interpretation of Sections 15 and 16. - - If the disclaimer of warranty and limitation of liability provided -above cannot be given local legal effect according to their terms, -reviewing courts shall apply local law that most closely approximates -an absolute waiver of all civil liability in connection with the -Program, unless a warranty or assumption of liability accompanies a -copy of the Program in return for a fee. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -state the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software: you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation, either version 3 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program. If not, see . - -Also add information on how to contact you by electronic and paper mail. - - If the program does terminal interaction, make it output a short -notice like this when it starts in an interactive mode: - - Copyright (C) - This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, your program's commands -might be different; for a GUI interface, you would use an "about box". - - You should also get your employer (if you work as a programmer) or school, -if any, to sign a "copyright disclaimer" for the program, if necessary. -For more information on this, and how to apply and follow the GNU GPL, see -. - - The GNU General Public License does not permit incorporating your program -into proprietary programs. If your program is a subroutine library, you -may consider it more useful to permit linking proprietary applications with -the library. If this is what you want to do, use the GNU Lesser General -Public License instead of this License.

Areas where help matters most: - -- **New trackers & missing data** — copy [`src/data/trackers/_template.ts`](src/data/trackers/_template.ts), fill in what you know, and submit a PR. Partial entries are fine — set `draft: true` and CI will accept it. Filling in user classes, rules, release groups, and banned groups on existing trackers is just as valuable. -- **Download client adapters** — only qBittorrent is supported. Deluge, Transmission, and rTorrent all need adapters. See `src/lib/qbt/` for the pattern. -- **Tracker verification** — if you belong to a tracker marked 🟡 above, testing and confirming it works helps greatly. -- **Security auditing** — Check out SECURITY.md for threat surfice info. -- **Responsiveness** - I only have my 16" MBP to work off of, so feedback of different screen experiences is much appreciated -- **Data Visualization** - I ain't no math wizard, so any contributions for data viz, charts/graphs, etc. -- **Custom platform adapters** — trackers marked "Custom" need bespoke adapters since they don't run a supported platform. -- **HawkeUno lobbying** — convince the Hawke mods to add a `/users` endpoint so the adapter can work - -## Architecture - -- **Next.js 16** (App Router) -- **PostgreSQL** + **Drizzle ORM** -- **ECharts** -- **node-cron** -- **Argon2** -- **jose** - -## License - -[GPL-3.0](LICENSE) diff --git a/SECURITY.md b/SECURITY.md deleted file mode 100644 index 5692a7cd..00000000 --- a/SECURITY.md +++ /dev/null @@ -1,565 +0,0 @@ - - -# Security Architecture - -Last audited: `2026-03-17` - -- [Security Architecture](#security-architecture) - - [For Users](#for-users) - - [Authentication](#authentication) - - [Data Classification](#data-classification) - - [Encryption at Rest](#encryption-at-rest) - - [Route Protection](#route-protection) - - [Data Protection](#data-protection) - - [Input Validation](#input-validation) - - [Security Response Headers](#security-response-headers) - - [Threat Model](#threat-model) - - [Is There Any Telemetry Baked In?](#is-there-any-telemetry-baked-in) - - [Username Privacy Mode](#username-privacy-mode) - - [Known Limitations](#known-limitations) - - [Unmitigated Attack Vectors](#unmitigated-attack-vectors) - - [1.

Secret encrypted at rest with AES-256-GCM. Stateless enrollment via JWE setup tokens (5min TTL). -- **Backup codes**: 8 codes in XXXX-XXXX hex format, hashed with SHA-256 + random salt, encrypted at rest. Each code is single-use. -- **Two-step login**: When TOTP is enabled, login returns a pending token (60s JWE). The client sends the pending token + TOTP code to complete authentication. -- **Auth model**: No whitelist or bypass — every API route independently calls `authenticate()`, which decrypts the JWE session. - ---- - -### Data Classification - -| Data | Storage | Encrypted | Justification | -| ---------------------- | --------------------------------------- | --------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------- | -| Master password | `app_settings.password_hash` | Argon2 hash (irreversible) | Memory-hard KDF; cannot be reversed | -| Tracker API tokens | `trackers.encrypted_api_token` | AES-256-GCM | Most sensitive field; provides account access | -| Encryption key | JWE session cookie + scheduler memory | JWE (A256GCM) | In-memory copy zero-filled on destructive operations; wrapped copy persisted in DB for boot recovery | -| Scheduler key | `app_settings.encrypted_scheduler_key` | AES-256-GCM (wrapped with HKDF-derived key from SESSION_SECRET) | Enables 24/7 polling; persists through logout; cleared on lockdown/nuke/password-change | -| Encryption salt | `app_settings.encryption_salt` | No | Salt is not secret; useless without master password | -| Tracker names | `trackers.name` | No | User-assigned label; not inherently identifying | -| Tracker base URLs | `trackers.base_url` | No | Reveals which trackers the user monitors | -| Tracker usernames | `tracker_snapshots.username` | No | Fetched fresh from tracker API on each poll | -| User class/group | `tracker_snapshots.group_name` | No | Fetched fresh from tracker API on each poll | -| Upload/download stats | `tracker_snapshots.*_bytes` | No | Numeric time-series; meaningful only with context | -| Ratio, seedbonus, H&Rs | `tracker_snapshots.*` | No | Numeric time-series; meaningful only with context | -| Session cookie | Browser (`tt_session`) | JWE (A256GCM) | httpOnly, secure, sameSite=strict | -| TOTP secret | `app_settings.totp_secret` | AES-256-GCM | TOTP enrollment secret; compromised = account takeover | -| Proxy password | `app_settings.encrypted_proxy_password` | AES-256-GCM | Proxy service credential | -| qBT credentials | `download_clients.encrypted_*` | AES-256-GCM | Download client authentication | -| Backup files | Filesystem (optional) | AES-256-GCM (optional) | Contains all data including encrypted fields as ciphertext | - -**Disk seizure note:** If an adversary accesses the raw database files, all unencrypted fields above are readable. Deploy on an encrypted filesystem (LUKS, dm-crypt, or equivalent). See [Known Limitations](#known-limitations). - ---- - -### Encryption at Rest - -All tracker API tokens are encrypted before database storage — `src/lib/crypto.ts`. - -| Parameter | Value | -| -------------- | --------------------------------------------------------- | -| Algorithm | AES-256-GCM | -| Key derivation | scrypt (N=16384, r=8, p=1) | -| IV | 12 bytes random per encryption | -| Auth tag | 16 bytes | -| Salt | 32 bytes random, stored in `app_settings.encryption_salt` | - -The encryption key is derived from the master password on login and stored in the encrypted JWE session. It is never persisted to disk in plaintext. - -The scheduler key (used to decrypt API tokens during background polling) is wrapped with a separate HKDF-derived key from `SESSION_SECRET` and stored in `appSettings.encryptedSchedulerKey`. This enables polling to run 24/7, surviving both container restarts and user logouts. The key is only cleared on destructive operations: lockdown, nuke, password change, and restore. If `SESSION_SECRET` is rotated, the stored key becomes undecryptable and polling will resume after the next login. - ---- - -### Route Protection - -Authentication is enforced at three independent levels: - -1. **Proxy** (`src/proxy.ts`): Checks for `tt_session` cookie on all non-public routes. Returns 401 for API routes; redirects to `/login` for pages. -2. **Route handlers**: Each API route calls `authenticate()` from `src/lib/api-helpers.ts`, which decrypts and validates the full JWE token. -3. **Layout guard** (`src/app/(auth)/layout.tsx`): Server Component calls `getSession()` before rendering any authenticated page. - -Public routes are explicitly limited to: `/login`, `/setup`, `/api/auth/*`, `/api/health`. - ---- - -### Data Protection - -- `encryptedApiToken` is never included in API responses — `serializeTrackerResponse()` in `src/lib/tracker-serializer.ts` uses an allowlist pattern; the token is structurally unreachable from the response object. -- All database queries use Drizzle ORM (parameterized queries, no SQL injection surface). -- No unsafe HTML injection methods anywhere in the codebase. -- **Emergency lockdown** (`POST /api/settings/lockdown`): Stops scheduler, revokes all API tokens, rotates encryption salt, wipes TOTP/username, destroys session. Requires active session and three-checkbox UI acknowledgment. -- **Scrub & delete** (`POST /api/settings/nuke`): Overwrites sensitive columns with random bytes, then deletes all rows. Requires active session + master password. Disk reclamation handled by PostgreSQL autovacuum. -- **Backup/restore**: Pure JSON format (no zip/tar). Restore validates all fields before database writes. File deletion uses `path.resolve()` + base directory prefix check. Restore requires master password re-confirmation. Encrypted fields travel as ciphertext. See [Backup Security](#backup-security). -- External HTTP requests use `AbortSignal.timeout(15_000)` — `src/lib/adapters/unit3d.ts:29`. -- Error messages sanitize hostnames and do not leak full URLs containing API tokens. - ---- - -### Input Validation - -All API routes validate inputs — `src/app/api/trackers/route.ts`, `src/app/api/trackers/[id]/route.ts`. - -| Field | Constraint | -| --------------- | ---------------------------------------------------------------------------------------------- | -| Tracker name | string, max 100 chars, trimmed | -| Base URL | string, max 500 chars, validated via `new URL()`, scheme restricted to `https://` or `http://` | -| API token | string, max 500 chars | -| Color | hex color format only (`#[0-9a-fA-F]{3,8}`), rejects arbitrary strings | -| qBittorrent tag | string, max 100 chars, trimmed | -| Poll interval | integer, clamped to 15-1440 minutes | -| Tracker ID | parsed as integer, NaN rejected | -| Platform type | allowlist: `["unit3d", "gazelle", "ggn", "nebulance", "avistaz", "mam", "custom"]` | -| Password | string, 8-128 chars | -| Role name | string, max 255 chars | -| joinedAt | regex-validated YYYY-MM-DD or null | -| Notes (roles) | string, max 2000 chars | - ---- - -### Security Response Headers - -Configured in `next.config.ts` for all routes: - -- `X-Content-Type-Options: nosniff` -- `X-Frame-Options: DENY` -- `X-XSS-Protection: 0` (disables legacy XSS auditor; prevents IE/Edge quirks) -- `X-DNS-Prefetch-Control: off` (prevents DNS prefetching which can leak browsing activity) -- `Referrer-Policy: strict-origin-when-cross-origin` -- `Permissions-Policy: camera=(), microphone=(), geolocation=()` - ---- - -### Threat Model - -| Property | Description | -| ---------------- | ----------------------------------------------------------------------------------------- | -| User model | Single user, self-hosted | -| Deployment | Docker Compose (open-source) | -| Trust boundary | Network perimeter; may be internet-facing behind reverse proxy | -| Primary threats | Unauthorized access, credential leakage, supply chain | -| External calls | User-configured tracker URLs (UNIT3D, Gazelle, GGn, Nebulance APIs) + qBittorrent clients | -| Data sensitivity | Tracker API tokens (encrypted), usage statistics | - ---- - -### Is There Any Telemetry Baked In? - -Nope 😎 - ---- - -### Username Privacy Mode - -Optional privacy mode (`Settings → Store Usernames`) controls whether tracker usernames and user classes are persisted to the database. - -| Mode | Behavior | -| --------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- | -| **Enabled** (default) | Usernames and groups are stored as-is in `tracker_snapshots` | -| **Disabled** | Usernames and groups are replaced with a length-preserving mask (`▓N` where N = character count) before database write. Real values are never stored. | - -When disabling, you can optionally scrub historical data to retroactively replace all previously stored usernames with their masked equivalents. - -The character-count mask is not strong anonymization. An investigator with database access could cross-reference the character count with ratio, upload volume, and user class to narrow down the account. For stronger protection, combine privacy mode with full-disk encryption (see [Deployment Hardening](#deployment-hardening)). - -The test-connection flow (`POST /api/trackers/test`) always returns the real username for confirmation. This value is ephemeral — displayed in the browser, never written to the database. - ---- - -### Known Limitations - -1. **Progressive lockout only (no IP-based rate limiting)**: Failed login and TOTP attempts trigger escalating lockouts (5 attempts → 30s, 10 → 2min, 15 → 15min, 20 → 1hr) via `getProgressiveLockoutMs()` in `src/lib/wipe.ts`. The counter is global (not per-IP), so an unauthenticated attacker can lock out the legitimate user. Deploy behind a reverse proxy with per-IP rate limiting on `/api/auth/login` for additional protection. -2. **API token in URL parameter**: UNIT3D (`?api_token=TOKEN`) and GGn (`?key=TOKEN`) pass tokens in the query string, which may appear in the tracker's server access logs. Gazelle trackers use `Authorization` headers (not logged by default). Upstream limitation. -3. **No CSP header**: Content Security Policy is not yet configured due to ECharts canvas rendering complexity. Basic headers (X-Frame-Options, X-Content-Type-Options) are in place. -4. **Optional 2FA**: TOTP is available but not required. Backup codes use SHA-256 + random salt (not Argon2 — high-entropy generated codes don't need memory-hard KDF). -5. **DNS rebinding not mitigated at fetch time**: SSRF protection validates hostnames when tracker URLs are saved, not when outbound requests are made. See [Unmitigated Attack Vectors](#6-dns-rebinding) for details. -6. **Scheduler key persisted in DB**: The encryption key is wrapped with an HKDF-derived key from `SESSION_SECRET` and stored in `appSettings` to enable 24/7 polling. An attacker with both database access and `SESSION_SECRET` could unwrap the key and decrypt all API tokens. For Docker Compose deployments, `SESSION_SECRET` is in the same trust boundary as DB credentials. Deploy on an encrypted filesystem for defense against disk seizure. Rotating `SESSION_SECRET` invalidates the stored key — polling resumes after the next login. -7. **Client IP in auth logs**: Failed and successful login attempts include the client IP (from `CF-Connecting-IP` or the rightmost `X-Forwarded-For` entry) in server log lines. IPs are never stored in the database. To suppress, configure your reverse proxy to strip these headers before forwarding to the app, or set `LOG_LEVEL=error` to disable info/warn log events entirely. - ---- - -### Unmitigated Attack Vectors - -These vectors are not fully mitigated at the application layer. Apply the recommended countermeasures at the infrastructure level. - -#### 1. Disk Seizure / Physical Access - -**Risk:** Physical access to the server exposes all unencrypted database fields — tracker names, base URLs, usernames (unless privacy mode is enabled), and usage statistics. API tokens are AES-256-GCM protected, but all metadata is plaintext. - -**Countermeasure:** Deploy the Docker volume on a LUKS- or dm-crypt-encrypted partition. See [Deployment Hardening](#deployment-hardening). - -#### 2. Compromised Host / Memory Dump - -**Risk:** Root access to a running host allows process memory dumps. The scrypt-derived encryption key is held in scheduler memory for the session duration. With this key, all encrypted API tokens can be decrypted. - -**Countermeasure:** On scheduler stop (triggered by lockdown, nuke, password change, or restore), the encryption key buffer is explicitly zero-filled (`Buffer.fill(0)`). Logout does not zero the key — the scheduler persists through logout for 24/7 polling. V8 may have created internal copies during GC compaction, but those are not directly inspectable. Standard server hardening also applies: patched OS, SSH key auth, non-root container. - -#### 3. Correlation Attack on Masked Usernames - -**Risk:** The character-count mask (`▓7` for a 7-character username) combined with ratio, upload volume, and tracker name may allow cross-referencing against a tracker's user database. Private trackers typically have small populations (hundreds to low thousands), making this feasible. - -**Countermeasure:** Combine username privacy mode with full-disk encryption. Use the retention policy to limit historical data available for correlation. - -#### 4. Network Traffic Analysis - -**Risk:** Even over HTTPS, a network observer can see the IP addresses of tracker API endpoints, revealing which trackers the user monitors. - -**Countermeasure:** Route outbound traffic through a VPN or Tor. This is outside the application's scope. - -#### 5. Tracker-Side Logging - -**Risk:** UNIT3D uses `?api_token=TOKEN` and GGn uses `?key=TOKEN` — the full URL including the token appears in the tracker's server access logs. Gazelle uses `Authorization` headers (not logged by default). Upstream limitation. - -**Countermeasure:** None at the application level. Users should be aware that API tokens may appear in tracker server logs depending on the platform. - -#### 6. DNS Rebinding - -**Risk:** SSRF protection in `src/lib/network.ts` validates hostnames at configuration time, not at request time. An attacker with DNS control could register a domain that resolves to a public IP during validation, then change it to a private IP before the next poll cycle. - -**Countermeasure:** Low risk — single user, manually entered URLs. Deploy on an isolated network segment where the container cannot reach internal services. A future enhancement could add DNS resolution validation at fetch time. - ---- - -### Backup Security - -The backup/restore system (`src/lib/backup.ts`, `src/app/api/settings/backup/`) maintains the following invariants: - -#### Data Handling - -- **Encrypted fields travel as ciphertext** — `encryptedApiToken`, `totpSecret`, `encryptedProxyPassword`, `encryptedUsername`, `encryptedPassword` are never decrypted during backup generation. -- **Password hash excluded** — `app_settings.password_hash` is never included in backup files. The restoring user's current password is preserved. -- **Encryption salt included** — required to re-derive the encryption key from the master password after restore. -- **Failed login counter reset** — `failedLoginAttempts` is always set to 0 on restore, regardless of the backup's value. - -#### Authentication - -- All four backup routes (`export`, `restore`, `history`, `delete`) require a valid session via `authenticate()`. -- **Restore requires master password re-confirmation** — failed verification increments the failed login counter and triggers lockout. - -#### Optional Encryption Layer - -When `backupEncryptionEnabled` is true, the entire backup JSON is wrapped in an additional AES-256-GCM layer using the session's encryption key. An encrypted backup (`.ttbak`) can only be restored with the same master password that created it. - -#### Restore Safety - -- Restore executes inside a PostgreSQL transaction — any failure rolls back all changes. -- The scheduler is stopped before restore begins (encryption key zeroed). -- The session remains valid after restore. The current `encryptionSalt` and `passwordHash` are never overwritten — they are preserved in place. Encrypted fields are re-encrypted from the backup's salt to the current salt via `reencryptField()`. -- BigInt values are serialized as decimal strings (not JSON numbers) to avoid 53-bit integer truncation. - -#### File Security - -- Backup files are pure JSON — no zip/tar archives, eliminating zip slip attack surface. -- Scheduled backups write to a configurable directory with `mkdir({ recursive: true })`. -- File deletion validates the resolved path against `backupStoragePath` using `path.resolve()` + `startsWith(base + path.sep)`. -- On-demand exports are returned as a browser download and saved to the configured `backupStoragePath`. If the disk write fails, the browser download still proceeds. - ---- - -### Deployment Hardening - -- **Encrypted filesystem:** Mount the PostgreSQL data volume on a LUKS-encrypted partition. This is the most effective defense against disk seizure. -- **Non-root container:** The Dockerfile runs as `nextjs` (UID 1001). Verify with `docker exec whoami`. -- **Read-only filesystem:** Mount the application container root as read-only (`read_only: true` in docker-compose) with tmpfs for `/tmp`. -- **Network isolation:** Place PostgreSQL on an internal Docker network with no published ports. -- **Reverse proxy:** Deploy behind Nginx, Caddy, or Traefik with TLS termination and rate limiting on `/api/auth/login`. -- **`NODE_ENV=production`:** Required for Next.js production optimizations. Cookie `secure` flag is controlled separately via `BASE_URL` scheme or `SECURE_COOKIES=true`. -- **`SESSION_SECRET`:** Minimum 32 characters of cryptographically random data. Generate with: `openssl rand -base64 48`. - ---- - -### Vulnerability Reporting - -If you discover a security vulnerability: - -1. **Do NOT open a public issue** for critical/high severity findings. -2.

Authentication & Authorization - -- [ ] Every new API route calls `authenticate()` from `src/lib/api-helpers.ts` as its first operation -- [ ] No new public routes added without updating the proxy allowlist in `src/proxy.ts` (lines 12-14) -- [ ] `authenticate()` failure returns `NextResponse.json({ error }, { status: 401 })` — no fallthrough -- [ ] Destructive operations (nuke, lockdown, restore) require additional password verification beyond the session -- [ ] TOTP-protected flows use the pending token pattern (60s JWE), not direct session issuance -- [ ] New settings or admin actions do NOT bypass the three-layer defense: proxy -> layout -> route handler - -#### 2. Input Validation - -- [ ] All user-supplied strings have a maximum length (`str.length > N` -> 400) -- [ ] URL inputs validated with `new URL()` + scheme restricted to `http://` or `https://` -- [ ] Color inputs validated against hex pattern (`/^#[0-9a-fA-F]{3,8}$/`) -- [ ] Numeric inputs parsed and bounds-checked (poll interval clamped to 15-1440) -- [ ] Date inputs regex-validated (`/^\d{4}-\d{2}-\d{2}$/`) or null -- [ ] ID parameters parsed as integers with `Number()` + `Number.isNaN()` check -- [ ] Platform type validated against allowlist, not open string -- [ ] No user input concatenated into SQL — all queries use Drizzle ORM's parameterized API -- [ ] File paths from user input validated with `path.resolve()` + `startsWith(basePath + path.sep)` - -#### 3. XSS Prevention - -- [ ] Zero uses of unsafe HTML injection methods in source files (innerHTML assignment, etc.) -- [ ] Zero uses of code-injection-risk functions in source files -- [ ] All user data rendered through JSX interpolation (`{value}`), never as raw HTML -- [ ] ECharts tooltip `formatter` functions only render app-computed data, not raw user strings -- [ ] No script tags dynamically constructed from user input -- [ ] The static security audit (`scripts/security-audit.ts` check #2) passes - -#### 4. Encryption & Secrets - -- [ ] API tokens stored via `encrypt()` from `src/lib/crypto.ts` — never plaintext in the database -- [ ] `encryptedApiToken` excluded from ALL API response objects (grep for `// SECURITY` comments) -- [ ] `passwordHash` never included in API responses or backup exports -- [ ] Encrypted credentials (`encryptedUsername`, `encryptedPassword`, `encryptedProxyPassword`) excluded from responses -- [ ] Password change route re-encrypts all secrets with the new derived key -- [ ] `SESSION_SECRET` is at least 32 characters (checked at startup) -- [ ] No secrets in `console.log`, `console.error`, or logger calls — hostnames only, never full URLs with tokens -- [ ] Error messages from adapter-fetch sanitize to hostname only (no token leakage in stack traces) - -#### 5. Session Security - -- [ ] Session cookie set with: `httpOnly: true`, `sameSite: "strict"`, `secure: shouldSecureCookies()`, `path: "/"` -- [ ] Session has hard expiry (7 days) encoded in the JWE payload — not just cookie `maxAge` -- [ ] Destructive operations (lockdown, nuke, password change, restore) zero-fill the encryption key buffer and stop the scheduler. Logout preserves the scheduler for 24/7 polling. -- [ ] Login returns the encryption key only inside the JWE session — never in the response body -- [ ] Failed login attempts increment atomically via `recordFailedAttempt()` in `src/lib/wipe.ts` - -#### 6. External Requests - -- [ ] All outbound HTTP requests have a timeout (`AbortSignal.timeout(15_000)` or equivalent) -- [ ] Tracker URLs validated at creation time — no open redirects or protocol switching -- [ ] Proxy-required trackers (`useProxy: true`) throw if proxy is unavailable — no fallback to direct connection -- [ ] qBT client connections validate host/port — no SSRF via user-configured client addresses -- [ ] No user-controlled data in `Authorization` headers beyond the stored (encrypted) API token - -#### 7. Database Operations - -- [ ] All queries use Drizzle ORM — no raw SQL strings with interpolated values -- [ ] BigInt values serialized as decimal strings in JSON (not `Number()` which truncates at 2^53) -- [ ] Backup restore runs inside a transaction — partial failures roll back cleanly -- [ ] `scrubAndDeleteAll` overwrites sensitive columns with random bytes before deletion -- [ ] Failed login counter uses atomic SQL (update + returning) — no TOCTOU race - -#### 8. File Operations - -- [ ] File read/delete operations validate resolved path against base directory + `path.sep` -- [ ] Backup format is pure JSON — no zip/tar archives (eliminates zip slip surface) -- [ ] No shell commands with user-supplied arguments -- [ ] Scheduled backup filenames are server-generated (timestamp-based) — not user-controlled - -#### 9. Security Headers - -Verify in `next.config.ts`: - -- [ ] `X-Content-Type-Options: nosniff` -- [ ] `X-Frame-Options: DENY` -- [ ] `Referrer-Policy: strict-origin-when-cross-origin` -- [ ] `Permissions-Policy: camera=(), microphone=(), geolocation=()` -- [ ] `X-DNS-Prefetch-Control: off` - -#### 10. Docker & Deployment - -- [ ] Container runs as non-root user (UID 1001 `nextjs`) -- [ ] `NODE_ENV=production` set in Dockerfile (cookie `secure` flag derived from `BASE_URL`/`SECURE_COOKIES`, not `NODE_ENV`) -- [ ] PostgreSQL on internal network — no published ports -- [ ] No `.env` files tracked by git (checked by security audit #7) -- [ ] `scripts/reset-password-nuclear.mjs` not included in production Docker image - -#### Quick Verification Commands - -```sh -# Run static security audit (covers XSS, auth, secrets, headers) -npx tsx scripts/security-audit.ts - -# Verify all API routes authenticate (files missing authenticate/getSession) -grep -rL 'authenticate\|getSession' src/app/api/**/route.ts - -# Count security tests (must be >= 78) -pnpm test:run -- src/lib/__tests__/security.test.ts 2>&1 | grep 'Tests' -``` - ---- - -### Huntarr Anti-Pattern Checklist - -Comparison against the 21 vulnerabilities found in Huntarr v9.4.2 ([security

This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param observerOrNext Either an {@link Observer} with some or all callback methods,\n * or the `next` handler that is called for each value emitted from the subscribed Observable.\n * @param error A handler for a terminal event resulting from an error. If no error handler is provided,\n * the error will be thrown asynchronously as unhandled.\n * @param complete A handler for a terminal event resulting from successful completion.\n * @return A subscription reference to the registered handlers.\n */\n subscribe(\n observerOrNext?: Partial> | ((value: T) => void) | null,\n error?: ((error: any) => void) | null,\n complete?: (() => void) | null\n ): Subscription {\n const subscriber = isSubscriber(observerOrNext) ? observerOrNext : new SafeSubscriber(observerOrNext, error, complete);\n\n errorContext(() => {\n const { operator, source } = this;\n subscriber.add(\n operator\n ? // We're dealing with a subscription in the\n // operator chain to one of our lifted operators.\n operator.call(subscriber, source)\n : source\n ? // If `source` has a value, but `operator` does not, something that\n // had intimate knowledge of our API, like our `Subject`, must have\n // set it.
