Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Multiple distinct misconfigurations in provider/listener setup can allow unauthenticated access or cross-mechanism bypasses.
Security Misconfiguration: Firewall config mapping, entry point selection, and authentication provider registration were mis-scoped, leading to incorrect exception handling and auth behavior.
Weak Password Hashing: Default password encoder was weak; bcrypt is now enforced, but any custom encoder path may still be insecure.
