A comprehensive skill for identifying and exploiting Cross-Site Scripting (XSS) vulnerabilities in web applications. It systematically tests reflected, stored, and DOM-based contexts by injecting various JavaScript payloads. The process involves mapping all user input points, identifying output contexts (HTML body, attribute, JS string, etc.), and crafting payloads to bypass sanitization and Content Security Policy (CSP) protections, simulating real-world attacks like session hijacking and credential theft.
