FBps

FBps (Forbidden Bypass) is a fast HTTP fuzzer specifically designed for identifying access control bypass vulnerabilities (401/403) in web applications by generating varied HTTP requests across methods, URLs, and headers. Notable features include level-based scanning, URL and query parameter fuzzing, header manipulation, API version downgrades, and customizable output options, making it a robust tool for security testing and vulnerability discovery. This tool is accompanied by FBpsLab for local payload tuning and reproducible testing environments.
