Recurring patterns

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

SQL Injection: Large query or bind messages exceeding 4 GB can trigger an integer overflow during message size encoding, causing the payload to be split into multiple valid frontend/backend messages and enabling SQL injection.

Cryptographic Issues: Misconfiguration of SSL mode parameters can lead to weak cryptographic validation, where specified root certificates are ignored and InsecureSkipVerify is erroneously set to true under 'require' mode.
