Recurring patterns

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

Auth Bypass: Incomplete integration between the serverless web proxy adapter and Spring Security filters allowed requests to bypass standard authentication and session-validation checkpoints. Developers must ensure that mock session wrappers like ProxyHttpSession fully replicate container contract expectations to prevent filter evasion.

Information Disclosure: A regression in the function registry's message propagation logic failed to reference the correct sanitized parameters, allowing sensitive input headers to leak directly into output messages. Developers modifying message routing or transformation paths must verify that header-filtering utilities are always correctly bound to the final output payload.
