CVE-2026-79151Network attack vector

System access restriction bypass via crafted file

Published Aug 25, 2026 · Updated Aug 25, 2026

Improper input validation in Safe Browsing in Google Chrome before 152.0.7977.65 allows remote attackers to bypass system access restrictions. Google identifies a crafted file as the input, but the restricted issue record leaves the rejected property and faulty validation operation undisclosed. A target must process the crafted file in Chrome; the published record establishes a restriction bypass but does not specify the accessed resource.
