Preliminary research
Are your Sites Truly Isolated? Automatically Detecting Logic Bugs in Site Isolation Implementations
AI-collected research leads through 22 September 2026, including targeted additions between broader sweeps. Unranked, incomplete, not community-vetted, and subject to change.
Site Isolation confines each site to its own renderer process, leaving the browser process to track which process may act for which site; errors in that bookkeeping are Site Isolation bypasses. This work presents the first automatic detector: a leak sanitiser flagging cross-process data leaks, a process sanitiser for process-reuse bugs, and an IPC fuzzer simulating a compromised renderer. Four vulnerabilities were found in Chrome and Firefox, one giving full control of a victim site.
