About this skill

What it does

This skill enables AI agents to perform HTML injection testing by generating payloads and analyzing how applications render untrusted input. It helps identify vulnerabilities where malicious scripts or content could be embedded within the DOM structure.

When to use it

  • Auditing web applications for Cross-Site Scripting (XSS) flaws before deployment.
  • Validating user-submitted forms that dynamically update page content without sanitization.
  • Testing third-party widgets or embedded iframes for potential injection vectors.
  • Assessing the robustness of Content Security Policy (CSP) implementations against DOM-based attacks.

Key capabilities

  • Generates targeted HTML payloads to probe application boundaries.
  • Analyzes rendered output to detect successful script execution or content manipulation.
  • Provides feedback on whether specific input fields are vulnerable to injection attacks.

Example prompts

  • "Test this login form for HTML injection vulnerabilities by submitting various payload types."
  • "Analyze the provided web page source and identify potential DOM-based XSS entry points."
  • "Generate a list of safe yet effective HTML payloads to test the comment section on this site."

Tips & gotchas

Ensure you have explicit authorization from the application owner before running injection tests, as these techniques can be used maliciously. Always review generated payloads carefully to avoid accidentally introducing harmful code into production environments during development testing.
