AI Analysis
Technical Summary
CVE-2026-11062 is a vulnerability in Google Chrome's extension policy enforcement mechanism affecting versions before 149.0.7827.53. The insufficient enforcement allows a malicious Chrome extension, installed by social engineering, to inject scripts or HTML into privileged browser pages. This could lead to limited integrity impacts within the browser context. The vulnerability is tracked under CWE-602 (Insufficient Control of Functionality).
Potential Impact
The vulnerability allows an attacker to inject scripts or HTML into privileged pages via a malicious extension, potentially altering the content or behavior of these pages. The CVSS score of 4.3 indicates a medium impact primarily on integrity, with no direct confidentiality or availability impact reported. There are no known exploits in the wild at this time.
Mitigation Recommendations
Google has released Chrome version 149.0.7827.53 to address this vulnerability. Users and administrators should update to this version or later to remediate the issue. Since this is a client-side application, patching the browser is the recommended mitigation. No additional vendor advisory states alternative mitigations or that no action is required.
