Recurring patterns

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

Auth Bypass: Peer certificate identity parsing can fail to match authorized principals if the Common Name (CN) is multi-valued and parsed as an array by the Node.js TLS module, leading to authorization bypass.

Auth Bypass: Improper construction of the secure context in server credentials can cause mutual TLS client certificate requirements to be silently ignored, permitting unauthenticated client connections.

Improper Certificate Validation: Failing to check the 'authorized' property on established TLS sockets allows connections to proceed even when certificate chain verification fails, violating basic transport security boundaries.
