Recurring patterns

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

Denial of Service: Unsafe type assertions on the Envoy external processing response (`extprocv3.ProcessingResponse_RequestBody`) can trigger a nil-pointer dereference or panic when handling malformed JSON payloads. This directly crashes the gateway container.

Auth Bypass: Missing authorization filters and selector checks during Model Context Protocol (MCP) interactions allowed unauthorized tool discovery and execution. Implementing proper authorization rules and tool allowlist selectors is critical.

Auth Bypass: Failure to strip client-provided headers that match JWT claims before forwarding requests to backend MCP servers enabled header injection forgery and signature validation bypass.
