CVE-2024-7017Network attack vector

Sandbox escape via DevTools reload race

Published Nov 14, 2025 · Updated Feb 26, 2026

Race condition in DevTools in Google Chrome before 126.0.6478.182 allows remote attackers to escape the browser sandbox via crafted HTML. Page.reload can reload an unintended target when its request races with navigation because the command does not bind the reload to the expected loader identifier. A user must open the page; successful exploitation breaks browser isolation and exposes host confidentiality, integrity, and availability.
