Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Authorization bypasses occurred due to loose substring matching (using String.contains) when validating JWT claims against authorized roles or groups, allowing partially matching malicious inputs to gain unauthorized access.
Auth Bypass: A downstream authorization bypass was caused by the failure to propagate user role claims from verified JWTs into the auditInfo context, which downstream portal handlers rely upon for enforcement.
Cryptographic Issues: A configuration mismatch in the ExternalServiceHandler disabled TLS hostname verification by default, exposing outbound HTTP client traffic to potential Man-in-the-Middle (MitM) attacks.
