CVE-2026-19560Network attack vector

Sandboxed code execution via Blink use-after-free

Published Aug 11, 2026 · Updated Aug 11, 2026

Use after free in Blink in Google Chrome before 151.0.7922.137 allows remote attackers to execute code in the sandbox via crafted HTML. Google identifies a freed-object lifetime error in Blink, but the restricted bug report leaves the affected Blink object and stale-reference path undisclosed. A user must open attacker-controlled HTML; resulting code execution remains inside Chrome's renderer sandbox, with no published sandbox escape for this CVE.
