Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Multiple fixes in this component address authentication bypass by failing to validate transport parameters, connection IDs, or source tokens before accepting handshake state, enabling spoofing or unauthorized 0-RTT.
Authentication Bypass: The client handshake path had numerous missing signature verifications (RSA, ECDSA) and state-gating flaws, allowing acceptance of forged or expired server configs and premature crypto escalation.
Information Disclosure: Repeated fixes prevent leaking internal error details and reason phrases to remote peers before handshake completion, a recurring information disclosure channel.
