A curated collection of HTML5-related XSS attack vectors, test files, and hidden testing features, browsable at html5sec.org. It serves as a reference dataset for security researchers and penetration testers testing browser and web application XSS defenses.
Use cases
- find XSS payloads for testing a web app
- test browser XSS filters against HTML5 vectors
- get sample files for XSS testing
- look up vectors related to innerHTML
- learn about HTML5 security pitfalls
When to choose
- you need a comprehensive reference of XSS attack vectors
- you are doing browser or web app security testing
- you need test files in many formats for XSS research
When to avoid
- you need an automated vulnerability scanner
- you want a defensive library or sanitizer
- you need general security training beyond XSS
