Recurring patterns

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

Insecure TLS Configuration: Distrusted and compromised root certificates (such as TURKTRUST, TDC Internet Root, and GLOBALTRUST) within the CA bundle can allow Man-in-the-Middle (MitM) attacks or validation of untrustworthy certificates. Keeping the underlying PEM store current is the most critical defense mechanism.

Weak Cryptography: Exposing legacy entry points like old_where() that might point to obsolete trust roots (such as weak 1024-bit root certificates) exposes TLS clients to weakened cryptographic validation.
