Technical Analysis
CVE-2026-79053 is a vulnerability in Google Chrome's Lighthouse component before version 152.0.7977.65. It involves missing authorization checks that enable a remote attacker, who has already compromised the renderer process and leveraged social engineering, to bypass site isolation protections using a specially crafted HTML page. This issue is classified with medium security severity by Chromium but has a CVSS score indicating low severity.
Potential Impact
The vulnerability could allow an attacker with access to the renderer process and social engineering capabilities to bypass site isolation, potentially exposing data or functionality that site isolation is designed to protect. However, it does not impact confidentiality, integrity, or availability directly according to the CVSS vector, and requires user interaction and a compromised renderer process.
Mitigation Recommendations
