Site Isolation bypass via incorrect Network authorization
Published Aug 25, 2026 · Updated Aug 25, 2026
Incorrect authorization in Network in Google Chrome before 152.0.7977.65 allows remote attackers to bypass Site Isolation. Google has not published the specific Network authorization check or the untrusted field that it handles incorrectly. Exploitation requires a compromised renderer process and a crafted HTML page, and the resulting protection bypass weakens cross-site process isolation without a reported sandbox escape.
