Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Broken Cryptography: The platform-native trust store integration on Windows loaded certificates without verifying key usage constraints. This allowed non-TLS certificates (e.g., code signing or email certificates) to be trusted as valid TLS root certificates, exposing clients to potential man-in-the-middle attacks. Developers must ensure that native certificate stores are filtered by specific usage OIDs (specifically PKIX Server Auth) during loading.
