See how missing role checks allow regular users to access hidden administrative endpoints, execute privileged actions, or take over system functions.
Imagine a regular employee walking into the CEO's office and signing a company-wide financial directive simply because the door was unlocked and nobody asked to see their badge. In APIs, Broken Function Level Authorization (BFLA) happens when the server verifies if you are logged in, but fails to verify if your specific role (e.g., user vs. admin) is authorized to execute a specific function (like an HTTP DELETE, or accessing an /api/admin/* endpoint).
Real attacks exploit predictability and obscurity. Attackers guess administrative URLs (/api/v2/admin/users), intercept mobile app traffic to find hidden endpoints, or simply change a GET request to a PUT or DELETE to see if the server enforces role-based access control (RBAC) on the mutating action.
