Documentation

README

Excerpt

Exploiting Broken Function Level Authorization

When to Use

Testing whether regular users can access administrative API endpoints by direct URL access
Assessing APIs for vertical privilege escalation where users can invoke functions above their role
Evaluating if API gateways and middleware consistently enforce function-level access controls
Testing role-based access control (RBAC) implementation across all API endpoints and HTTP methods
Validating that API documentation does not expose admin endpoint paths that lack authorization

Do not use without written authorization. BFLA testing involves attempting to execute administrative functions with unauthorized credentials.
