Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: JWT verification relied on an unvalidated certificate source, allowing potential key confusion or substitution attacks.
Auth Bypass: OAuth authorization code exchange lacked PKCE, leaving the flow vulnerable to interception and replay attacks.
Cache Poisoning: Cache revalidation did not strip hop-by-hop headers or normalize header case, enabling response cache poisoning.
