Attack-Flow Graph

Executive Summary

This vulnerability involves missing authorization in the ReadingMode feature of Google Chrome before version 155.0.8059.79. A remote attacker who already compromised the renderer process could exploit this by tricking a user into visiting a crafted HTML page. This could potentially bypass site isolation protections.

Impact Analysis

If exploited, this vulnerability could allow an attacker to bypass site isolation, potentially accessing data from other sites you are logged into. This could lead to unauthorized access to sensitive information like passwords or personal data.

Compliance Impact

This vulnerability could lead to unauthorized data access, which may violate GDPR's data protection requirements or HIPAA's safeguards for protected health information. Organizations using vulnerable Chrome versions may face compliance risks.
