Technical Analysis
CVE-2026-78979 is a race condition vulnerability in the Core of Google Chrome on Windows platforms before version 152.0.7977.65. This flaw enables a remote attacker, through social engineering and a specially crafted HTML page, to bypass the web origin policy, potentially allowing unauthorized access to web content. The Chromium security team rates this vulnerability as low severity, and the CVSS v3.1 base score is 4.3 (medium).
Potential Impact
The vulnerability allows bypassing the web origin policy, which is a fundamental security control in browsers to isolate content from different origins. This could lead to unauthorized access to web resources or data within the browser context. However, the impact is limited to confidentiality (partial information disclosure) with no integrity or availability impact, and exploitation requires user interaction (UI:R).
Mitigation Recommendations
A fixed version of Google Chrome addressing this vulnerability is available starting from version 152.0.7977.65. Users and administrators should update to this version or later to remediate the issue. The vendor advisory confirms the fix is included in this update.
