CVE-2026-19152Network attack vector

Sandbox escape via Navigation policy failure

Published Aug 6, 2026 · Updated Aug 6, 2026

Sandbox escape in Google Chrome before 151.0.7922.109 allows remote attackers to cross the browser security boundary via crafted HTML. The Navigation component insufficiently enforces an undisclosed policy after renderer compromise; Google keeps the underlying bug details restricted. Exploitation requires user interaction with the page and prior renderer compromise, after which the attacker gains capabilities outside the renderer sandbox.
