Abusing postMessage API for 6 figures/year
The postMessage API is a very versatile option for achieving secure communication between different browser windows, generally used for bypassing same-origin policy restrictions. It is generally used in complex, functionality-rich web applications and has the potential to streamline complex business flows, but is also very often poorly implemented. This presentation will highlight tens of postMessage vulnerabilities found in the last year, varying from XSS issues to account takeovers. Millions of people potentially affected, cool stories, big bounties, not-very-fixed vulnerabilities. Everything is vulnerable, from web chats to payment flows, from some of our favorite Romanian companies to global giants that power our everyday activities.
