Episode 68: In this episode of Critical Thinking - Bug Bounty Podcast Mathias is back with some fresh HTMX research, including CSP bypass using HTMX triggers, converting client-side response header injection to XSS, bypassing HTMX disable, and the challenges of using HTMX in larger applications and the potential performance trade-offs. We also talk about the results of his recent CTF Challenge, and explore some more facets of CDN-CGI functionality.
