# Broken Function Level Authorization
Hunt for endpoints where authorization is enforced at the controller/middleware level but bypassed through HTTP verb drift, legacy routes, shadow endpoints, or transport protocol inconsistencies. Unlike IDOR (object-level), this targets ACTION-level authorization — can a user invoke admin functions despite lacking the admin role.
## When to Use
- API has distinct user roles (admin, moderator, user) but role checks are per-controller, not per-method.
- Legacy or deprecated endpoints still served behind updated middleware.
- GraphQL, gRPC, and WebSocket transports exist alongside REST APIs without authorization parity.
- Feature flags or beta endpoints expose functionality before security review.
- Batch/job endpoints accept internal requests without role verification.
## Quick Detection
