Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Unbounded resource allocation during script execution, gzip decompression, and outbound connection handling can pin threads and exhaust system memory. Developers must enforce strict timeouts and size limits across all parsers and engines.
Auth Bypass: Concurrent access to stateless validators can cause configuration overrides and race conditions, leading to complete authentication bypass. Thread-safe validation policies are critical.
Auth Bypass: User-defined catch-all expectations can preemptively match and hijack internal administrative endpoints if management prefixes are not explicitly exempted prior to evaluation.
