Episode 64: In this episode of Critical Thinking - Bug Bounty Podcast we talk about Justin and Joel delve into .NET remoting and how it can be exploited, a recent bypass in the Dom Purify library and some interesting functionality in the Cloudflare CDN-CGI endpoint. They also touch on the importance of collaboration and knowledge sharing, JavaScript Deobfuscation, the value of impactful POCs, hiding XSS payloads with URL path updates.
