Technical Analysis
CVE-2026-79006 describes a vulnerability in Google Chrome's HttpsUpgrades protection mechanism. Specifically, in versions prior to 152.0.7977.65, an attacker can bypass the web origin policy by sending crafted network traffic. The web origin policy is a critical security control that restricts how documents or scripts loaded from one origin can interact with resources from another origin. The vulnerability has a CVSS score of 4.3 (medium severity) and does not require privileges but does require user interaction. The vendor advisory from Google confirms the issue and the fixed version.
Potential Impact
An attacker can bypass the web origin policy, potentially allowing cross-origin interactions that should be restricted. This could lead to limited confidentiality breaches but does not impact integrity or availability. The attack requires user interaction and network access.
Mitigation Recommendations
Google has released an official fix in Chrome version 152.0.7977.65. Users and administrators should update to this version or later to remediate the vulnerability. No additional mitigation steps are indicated by the vendor advisory.
