Wfuzz

Wfuzz is an open-source web application fuzzer written in Python that facilitates security assessments by replacing FUZZ keywords with values from customizable payloads to inject test data into any HTTP request field including parameters, authentication headers, forms, directories, files, and cookies to identify vulnerabilities in web applications. The modular framework supports plugin-based vulnerability scanning with flexible payload sources including wordlists, ranges, and custom data generators, integrating seamlessly into penetration testing workflows to help security professionals discover and exploit web application vulnerabilities including SQL injection, XSS, directory traversal, and authentication weaknesses throughout security assessments.
