Usage & Best Practices

• Authorization Required: Only use these payloads for authorized security testing, penetration testing engagements, CTF challenges, or educational purposes.
• Testing Methodology: Start with simple payloads before trying complex ones. Test in isolated environments first.
• Context Matters: Different contexts (HTML, JavaScript, URL, CSS) require different payload types. Choose the appropriate context filter.
• WAF Testing: Use encoding and obfuscation techniques to test Web Application Firewall effectiveness.
• Documentation: Export payloads as Markdown for inclusion in security reports and documentation.
• Defense: Understanding attack vectors helps implement proper output encoding, CSP headers, and input validation.

Defense Recommendations

• Context-Aware Output Encoding: Encode data based on context (HTML, JavaScript, URL, CSS)
• Content Security Policy (CSP): Implement strict CSP headers to prevent inline scripts
• Input Validation: Validate and sanitize all user input using allowlists
• HTTPOnly Cookies: Set HttpOnly flag on session cookies
