Identify cross-site scripting attack surfaces by analyzing high-risk input points and recognition signals. This skill guides penetration testers in systematically mapping potential XSS entry vectors across target web applications.

Craft payloads to bypass Content Security Policy using detailed filtering bypass techniques and exploitation chains. The skill leverages HTML, JavaScript, and DOM manipulation knowledge to construct effective XSS payloads.

Stored, Reflected, and DOM-based XSS vulnerabilities differ in payload persistence and execution locations. This skill provides distinct exploitation techniques and detection checklists to systematically test each variant.

Assess the impact and severity of discovered XSS flaws by evaluating potential consequences using real-world HackerOne cases. This helps penetration testers accurately determine the risk level of cross-site scripting vulnerabilities.

To hunt for XSS vulnerabilities effectively, you need prerequisite knowledge of HTML, JavaScript, DOM manipulation, and security headers like CSP. This skill applies these concepts to payload crafting and attack surface discovery.
