Recurring patterns

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

Auth Bypass: LDAP authentication could be bypassed due to unescaped input queries and a lack of proper credential verification via a real LDAP bind sequence. Developers should ensure inputs are strictly escaped and that a real bind occurs.

Auth Bypass: Insecure inter-component communication could occur if mutual TLS (mTLS) with strict client certificate verification is not enforced, potentially allowing rogue proxies or gateways to authenticate.

Auth Bypass: Modified or unauthorized WireGuard devices could bypass MFA networks if the gateway fails to filter out unauthorized peers or disconnect sessions when MFA authorization checks fail.
