CVE-2026-79209Network attack vector

Sandboxed code execution via Animation type confusion

Published Aug 25, 2026 · Updated Aug 25, 2026

Type confusion in Chrome's Animation component before 152.0.7977.65 allows remote attackers to execute arbitrary code inside the sandbox. Google identifies the affected component and weakness class but has not published the erroneous type operation or triggering object sequence. Exploitation requires a user to open a crafted HTML page; no authentication is required, and the reported code execution remains sandbox-contained.
