Does this skill perform actual automated attacks?

It provides the specific methodologies, payloads, and step-by-step guidance for testing, but execution requires the user to have authorized access and follow legal boundaries.

Are remediation steps included for discovered vulnerabilities?

Yes, the skill provides clear remediation recommendations, including output encoding best practices, input validation strategies, and secure CSP configurations.

Can it help bypass modern Content Security Policies (CSP)?

Yes, it includes techniques to identify common CSP misconfigurations and provides specific payloads designed to test for bypasses in various policy environments.

Does it support detection of DOM-based XSS?

Absolutely. It identifies dangerous JavaScript sinks like innerHTML and eval(), as well as user-controllable sources like location.hash, to find vulnerabilities that occur entirely in the browser.

セキュリティとテスト

Automates the identification and exploitation of Cross-Site Scripting (XSS) and HTML injection vulnerabilities in web applications.

概要

This skill provides a comprehensive framework for security professionals and developers to perform deep client-side injection audits. It guides users through systematic detection phases for stored, reflected, and DOM-based vectors, offers an extensive library of bypass techniques for modern filters, and generates proof-of-concept payloads for demonstrating impact such as session hijacking or credential theft. Beyond exploitation, it includes actionable remediation guidance and Content Security Policy (CSP) configurations to help secure applications against future attacks.
