Episode 26: Client-side Quirks & Browser Hacks

In this episode of Critical Thinking - Bug Bounty Podcast, we're back with Joel, fresh (haha) off of back-to-back live hack events in London and Seoul. We compare the different vibes of each LHE, then we dive into the technical thick of it, and talk web browsers, XSS vectors, new tools, CVSS 4.
