Wapiti

Wapiti is a black-box web application vulnerability scanner that crawls target websites and injects payloads to detect security flaws without requiring access to the application's source code. It tests for a comprehensive range of vulnerabilities including SQL injection, cross-site scripting (XSS), file inclusion, command injection, XXE, SSRF, and open redirects through its modular fuzzer architecture. Penetration testers and security assessors use Wapiti as an automated first pass during web application assessments to identify low-hanging vulnerabilities and map the application's attack surface. Written in Python with support for authenticated scanning and multiple output formats, it serves as a free and open-source alternative to commercial web scanners like Acunetix and Burp Suite Pro.
