What problem does it solve?
XSS vulnerabilities in web applications pose significant security risks, including session hijacking, data leakage, and unauthorized actions. This skill provides a comprehensive framework for identifying, validating, and documenting XSS findings with concrete guidance for safe, authorized testing and responsible disclosure.
Core Features & Use Cases
- Comprehensive testing patterns: Coverage of reflected, stored, and DOM-based XSS vectors across web apps, APIs, and document rendering pipelines.
- Risk-informed storylines: Real-world impact scenarios and chain analyses to help prioritize remediation and escalate findings appropriately.
- Responsible testing guidance: Best practices for safe, permission-based testing, evidence collection, and coordination with stakeholders.
