CVE-2026-15113Network attack vector

Sandbox escape via Autofill use-after-free

Published Jul 8, 2026 · Updated Jul 8, 2026

Use-after-free in Google Chrome for Android before 150.0.7871.115 allows remote attackers to escape the browser sandbox via crafted HTML. Autofill code accesses an object after its memory has been freed; the restricted issue record leaves the exact lifetime error and trigger undisclosed. Exploitation requires a user to load attacker-controlled HTML, after which browser sandbox isolation is lost.
