Recurring patterns

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

Auth Bypass: Connection desynchronization occurring from early returns of connections on HTTP 1xx interim responses can cause responses to be misrouted to incorrect clients, leading to severe information exposure or authentication bypass.

Auth Bypass: Lack of proper path normalization and premature URL decoding in routing filters allows directory traversal (dot-dot-slash) and unauthorized query parameter injection, bypassing gateway routing rules.

Denial of Service: Unhandled exceptions or null values during TLS SNI parsing inside the SSL handshake handler can lead to connection drops and denial of service.
