CVE-2026-11223 is a vulnerability in Google Chrome prior to version 149. 0. 7827. 53 involving insufficient validation of untrusted input in the network component. This flaw allows a remote attacker who has already compromised the renderer process to bypass the same origin policy by using a crafted HTML page. The Chromium security team has rated this vulnerability as low severity. There is no explicit vendor advisory stating patch availability or mitigation details beyond the version information. No known exploits in the wild have been reported.
AI Analysis
Technical Summary
This vulnerability in Google Chrome's network component prior to version 149.0.7827.53 results from insufficient validation of untrusted input. An attacker with control over the renderer process can exploit this to bypass the same origin policy via a crafted HTML page. The same origin policy is a critical security mechanism that restricts how documents or scripts loaded from one origin can interact with resources from another origin. Bypassing this policy can lead to unauthorized access to sensitive information across origins. The issue is rated low severity by the Chromium security team. No CVSS score is assigned, and no explicit remediation level is provided in the available data. The vendor advisory link points to a stable channel update announcement but does not explicitly confirm patch status for this specific vulnerability.
Potential Impact
The impact is limited to scenarios where an attacker has already compromised the renderer process in Chrome. Exploitation allows bypassing the same origin policy, potentially enabling unauthorized cross-origin data access. However, the overall severity is considered low by the Chromium security team, indicating limited risk or difficulty in exploitation. There are no known exploits in the wild at this time.
Mitigation Recommendations
The vulnerability affects versions of Chrome prior to 149.0.7827.53. Users and administrators should update to version 149.0.7827.53 or later to address this issue. The vendor advisory linked is a stable channel update announcement, which implies that the fix is included in the stated version. Patch status is therefore considered available via updating to this version. No additional mitigation steps are specified by the vendor.
