In this talk, we’ll look at a new threat in web application security — JavaScript prototype pollution. First, we’ll get a deep dive into workings of JavaScript objects and classes. On this basis, we’ll explore what JavaScript prototype pollution is and how it can be found in the client side. After this, we’ll look at ways to exploit prototype pollution once you’ve found it. We’ll share our bug bounty experience, cool stories about bypassing fixes and finding edge cases.
