FileUpload Gunner Project

The is more than just a script; it is a mindset. It forces developers and security professionals to treat every file upload as a potential zero-day exploit waiting to happen. By integrating this tool into your security arsenal—whether for red teaming, blue team hardening, or CI/CD testing—you can transform the most dangerous vulnerability in your web app into a well-defended perimeter. Iteration 1 (Extension Fuzzing): Renames the file to
