Module Documentation

Detailed module-level usage and examples are available in:

• DOCUMENTATION.md

---

Vulnerable Web Application

SecurityNexus includes a deliberately vulnerable Flask web application for practice:

cd vulnerable_webapp
python app.py
# Access at http://localhost:5000

Available vulnerabilities include SQL Injection, XSS, CSRF, command injection, insecure file upload handling, and IDOR patterns.
