Executive Summary

This vulnerability is due to insufficient policy enforcement in the Autofill feature of Google Chrome versions before 151.0.7922.72. A remote attacker could exploit this by creating a specially crafted HTML page to trick the browser into leaking data across different origins.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 151.0.7922.72. Detection involves checking the installed Chrome version. On Windows, run: wmic product where name='Google Chrome' get version. On Linux, check via: google-chrome --version or dpkg -l | grep google-chrome. If the version is below 151.0.7922.72, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to access sensitive cross-origin data, such as form inputs or personal information, that should normally be restricted. This could lead to privacy breaches or unauthorized data exposure.

Compliance Impact

This vulnerability could potentially violate data protection regulations like GDPR or HIPAA by enabling unauthorized access to personal or sensitive data. Organizations using vulnerable Chrome versions may face compliance risks and legal consequences.

Mitigation Strategies

Update Google Chrome to version 151.0.7922.72 or later to address the insufficient policy enforcement in Autofill.
