Recurring patterns

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

CWE-300: Man-in-the-middle packet injection is possible if the driver fails to validate trailing bytes during the SSL handshake negotiation, allowing arbitrary commands to be buffered prior to encryption.

Auth Bypass: Lack of enforcement for SASL SCRAM channel binding modes exposes client connections to silent downgrade attacks where a MITM proxy can relay authentication credentials.

Improper Certificate Validation: Failure to properly sanitize and reject trailing dots in configured hostnames can result in SNI mismatch or bypassed certificate validation logic.
