Recurring patterns

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

Auth Bypass: The application failed to enforce password verification constraints and incorrectly parsed multiline authentication responses, allowing potential authentication bypass. It also previously skipped cryptographic decryption verification before renewing or discarding expired tokens.

Denial of Service: Uncaught socket-level exceptions, missing request timeouts, and unhandled decryption errors during the authentication loop regularly caused the proxy server to hang, crash, or loop indefinitely.

Injection: Insufficently validated IMAP command tags allowed injection payloads through control and space characters into compilation routines.
