Testing BFLA involves identifying admin endpoints, testing access with regular user credentials, and manipulating HTTP methods or parameters to check if role-based access controls are properly enforced.

Broken Function Level Authorization is an API vulnerability where regular users can access administrative functions or privileged endpoints without proper authorization, enabling privilege escalation and unauthorized access.

You can verify role-based permissions by testing API endpoints with different user credentials, manipulating HTTP methods, and altering request parameters to confirm regular users cannot access privileged functions.

Yes, you can use Python with the requests library to automate BFLA testing. The scripts send HTTP requests with various user tokens to identify admin endpoints and test for privilege escalation vulnerabilities.

HTTP method manipulation tests whether API authorization depends on the method used. Changing GET to PUT or DELETE can sometimes bypass broken function level authorization and grant unauthorized access.

The best way to find vulnerable admin endpoints is using automated discovery scripts that test common admin patterns, check older API versions, and attempt path traversal techniques to bypass authorization controls.
