Sensitive information disclosure via extension authorization bypass
Published Sep 9, 2026 · Updated Sep 10, 2026
Incorrect authorization in Google Chrome before 153.0.8010.36 allows remote attackers to obtain sensitive information via a crafted extension. The Permissions component grants an attacker-supplied Chrome extension access without the required authorization; Google has not disclosed the specific code locus or data exposed. Exploitation requires social engineering that causes the crafted extension to run, and the documented consequence is limited to sensitive-information disclosure.
