CVE-2026-91724Network attack vectorHinoki check available

Sandbox escape via Input use-after-free

Published Sep 15, 2026 · Updated Sep 15, 2026

Use-after-free in Chrome's Input component before 153.0.8010.47 allows remote attackers to execute arbitrary code outside the sandbox. Google identifies Input as the affected component but has not published the freed object's identity or the operation that reuses it. Exploitation requires a crafted HTML page and prior compromise of the renderer process; successful reuse crosses the browser sandbox boundary.
