Sensitive information disclosure
Published Mar 9, 2021 · Updated Aug 3, 2024
Insufficient policy enforcement in Google Chrome before 89.0.4389.72 allows attackers to obtain sensitive information through a crafted extension. Public records identify the Extensions component but do not disclose which policy check is missing or what protected data the extension can read. Exploitation requires a user to install the malicious extension, and the documented consequence is limited to sensitive-information disclosure.
