CVE-2025-12726Network attack vector

Renderer sandbox escape via undisclosed Views flaw

Published Nov 10, 2025 · Updated Nov 10, 2025

Privilege escalation in Google Chrome before 142.0.7444.137 allows remote attackers to escape a compromised renderer via crafted HTML. Google identifies Views as the affected component but has not published the erroneous operation or validation failure, and the linked issue remains restricted. Exploitation requires Windows, a renderer already under attacker control, and user interaction with the crafted page; success crosses the renderer sandbox boundary.
