We deep-dive a CSP bypass he found in GitHub, a critical he found in GitLab's pipeline, and also talk through his approach to using script gadgets and adapting to highly CSP'd environments. Then we talk about his transition to full-time bug hunting, including the goals he’s set, the successes and challenges, and his current focus on specific bug types like ReDoS and OAuth, and the serendipitous nature of bug hunting.
