Recurring patterns

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

Authentication Bypass: Missing signature verification on certificate chains allowed forged certificates to be accepted, a fundamental integrity failure.

Weak Cryptography: Support for SHA-1 signatures weakened authentication; removed to enforce modern cryptographic standards.

Certificate Name Constraints Bypass: dNSName constraints were not enforced, allowing certificates outside permitted namespaces to be accepted.
