CVE-2026-87475Network attack vector

Privileged-page access via missing Omnibox authorization

Published Sep 9, 2026 · Updated Sep 9, 2026

Missing authorization in Google Chrome's Omnibox before 153.0.8010.36 allows remote attackers to open a privileged page via crafted HTML. Google has not disclosed the specific Omnibox code path or the authorization check omitted when navigation to the privileged page is accepted. Exploitation requires social engineering that induces a user to interact with the crafted page; the demonstrated consequence is bypass of browser-enforced access restrictions.
