Preliminary research

BUIzz: Finding Policy Enforcement Bugs via Interaction Simulation on the Browser User Interface

Mingi Jung, Donggyu Kim, Mijung Kim and Seongil Wi · usenix.org

AI-collected research leads through 22 September 2026, including targeted additions between broader sweeps. Unranked, incomplete, not community-vetted, and subject to change.

Browsers enforce CSP, SameSite and similar headers, so a browser bug in enforcement silently removes the defence a site configured. BUIzz is the first framework to hunt those bugs through browser-user-interface interactions - open in split view, new window, private window - taken from browser manuals, context menus and past bugs, then simulated at OS level. It found a SameSite=Strict bypass in Brave.
