CVE-2026-87575Network attack vector

Access restriction bypass via incorrect Loader authorization

Published Sep 9, 2026 · Updated Sep 9, 2026

Incorrect authorization in Google Chrome Loader before 153.0.8010.36 allows remote attackers to bypass system access restrictions. Loader makes an incorrect authorization decision while processing a crafted HTML page; Google has not disclosed the affected function or exact resource boundary. Exploitation requires social engineering that causes a user to open the crafted page, and the published record does not identify which restricted system resource becomes accessible.
