CVE-2026-11027 is a medium severity vulnerability in Google Chrome prior to version 149.0.7827.53. It involves insufficient validation of untrusted input in the Glic component, allowing a remote attacker who has compromised the renderer process to leak cross-origin data via a crafted HTML page. The vulnerability has a CVSS score of 6.5 and does not impact integrity or availability. No known exploits are reported in the wild. A vendor advisory is available but does not explicitly confirm patch status.
AI Analysis
Technical Summary
This vulnerability in Google Chrome's Glic component arises from insufficient validation of untrusted input, which can be exploited by a remote attacker with control over the renderer process to leak cross-origin data. The issue affects Chrome versions prior to 149.0.7827.53. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high confidentiality impact. The vendor advisory linked does not explicitly state the availability of a patch or remediation level, so patch status is not confirmed.
Potential Impact
An attacker who has already compromised the renderer process can exploit this vulnerability to leak sensitive cross-origin data, potentially exposing confidential information. There is no impact on integrity or availability. No known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html for current remediation guidance. Until confirmation of a fix, users should exercise caution with untrusted content and consider updating to the latest Chrome version once a patch is confirmed.
