Episode notes
DOMPurify Comment Bypass Insight
- DOMPurify bypasses often stem from inconsistent comment handling between the sanitizer and browser.
- Simplifying complex bypasses to primitives aids reuse and understanding of XSS exploitation.
Use AI for Iterative Hacking
- Use iterative testing combined with AI models like O3 mini to optimize vulnerability discovery.
- Combine verbose error messages and past payload diffs to guide AI in generating new payloads.
Probe Authentication Deeply
- Investigate authentication mechanisms in chat or plugin systems deeply beyond simple ID swaps.
- Pay careful attention to API key usage to identify potential secret leaks and authorization flaws.
