+# Dependency Security Reports
+
+This directory tracks Rust dependency security scans for the deployer workspace.
+
+## Current Status
+
+- Last scan: 2026-04-10
+- Tool: `cargo-audit`
+- Status: no known RustSec vulnerabilities in `Cargo.lock`
+- Latest report: [scans/2026-04-10-cargo-audit.md](scans/2026-04-10-cargo-audit.md)
+
+## Scanning Standard
+
+- Run command: `cargo audit`
+- Record date, scanner output summary, and remediation actions.
+- If findings remain and cannot be fixed quickly, open a follow-up GitHub issue and link it in the report.
+
+## Related Automation

+# Cargo Audit Security Scan - 2026-04-10
+
+## Scan Metadata
+
+- Date: 2026-04-10
+- Tool: `cargo-audit`
+- Workspace: `torrust-tracker-deployer`
+- Command: `cargo audit`
+
+## Baseline (Before Remediation)
+
+Initial scan found 4 vulnerabilities and 1 warning:
+
+1. `RUSTSEC-2026-0066` - `astral-tokio-tar 0.5.6`
+1. `RUSTSEC-2026-0007` - `bytes 1.11.0`
+1. `RUSTSEC-2026-0049` - `rustls-webpki 0.103.8`
+1. `RUSTSEC-2026-0009` - `time 0.3.44`
+1. `RUSTSEC-2025-0134` - `rustls-pemfile 2.2.0` (unmaintained warning)
+
+Baseline output excerpt:
+
+```text
+error: 4 vulnerabilities found!
+warning: 1 allowed warning found
+```
+
+## Remediation Actions
+
+Applied updates:
+
+1. Upgraded `testcontainers` in workspace root from `0.26` to `0.27`.
+1. Upgraded `testcontainers` in `packages/dependency-installer` dev-dependencies from `0.25` to `0.27`.
+1. Refreshed lockfile with `cargo update`.
+
+These updates pulled patched transitive dependencies, including:
+
+- `bytes 1.11.1`
+- `time 0.3.47`
+- `rustls-webpki 0.103.10`
+
+## Verification (After Remediation)
+
+Command rerun:
+
+```bash
+cargo audit
+```
+
+Result:
+
+- Exit code: `0`
+- No vulnerabilities reported for current lockfile.
+
+Output excerpt:
+
+```text
+Fetching advisory database from `https://github.com/RustSec/advisory-db.git`
+Loaded 1042 security advisories
+Scanning Cargo.lock for vulnerabilities (380 crate dependencies)
+```
+
+## Follow-up Issues
+
+No follow-up issue was required for this scan because all reported vulnerabilities were resolved through dependency updates.
