• Max score is 1000. Note that the real score may have changed since the PR was raised.
• This PR was automatically created by Snyk using the credentials of a real user.
• Some vulnerabilities couldn't be fully fixed and so Snyk will still find them when the project is tested again. This may be because the vulnerability existed within more than one direct dependency, but not all of the affected dependencies could be upgraded.

[adamlaska]

This upgrade from cryptography 45.0.7 to 49.0.0 spans multiple major versions and includes significant breaking changes that require both code and environment updates.

Key Breaking Changes:

• Python Version Requirement: Support for Python 3.7 and 3.8 has been removed. This upgrade requires Python 3.9 or later. [1]
• OpenSSL Version Requirement: Support for OpenSSL 1.1.x is removed. OpenSSL 3.0.0 or later is now required. [1]
• API Removals: Several deprecated algorithms and modes have been removed and will cause code to fail if used:
  • TripleDES and ARC4 are removed from the cipher module as of v48.0.0. [2, 10]
  • CFB, OFB, and CFB8 are removed from the modes module as of v49.0.0. [2]
  • Camellia is removed from the cipher module as of v49.0.0. [2]
• Elliptic Curve Support: Support for binary elliptic curves (SECT* classes) was removed in v47.0.0. [1]
• Stricter Validation: As of v48.0.0, loading an X.509 CRL with a mismatched signature algorithm will now raise a ValueError. [1]

Recommendation:
Due to the multiple breaking changes, a careful review of your code is necessary. You must ensure your environment meets the new Python and OpenSSL version requirements. Any code using the removed ciphers or modes must be refactored. It is highly recommended to test this upgrade in a staging environment before deploying to production.
