The vulnerability is classified with high security severity by the Chromium project. No CVSS score is provided for this issue.
AI Analysis
Technical Summary
CVE-2026-12468 is a race condition vulnerability in the Updater of Google Chrome on Mac platforms before version 149.0.7827.155. It enables a remote attacker, with control over the renderer process, to potentially perform a sandbox escape through a crafted HTML page. This vulnerability could allow the attacker to break out of the browser's sandbox environment, increasing the risk of further system compromise. The Chromium project rates this vulnerability as high severity. The vendor advisory linked indicates a stable channel update addressing this issue, implying that version 149.0.7827.155 includes the fix.
Potential Impact
If exploited, this vulnerability could allow an attacker who has compromised the renderer process to escape the sandbox on Mac systems running affected Chrome versions. Sandbox escape can lead to execution of arbitrary code with higher privileges, increasing the potential damage from an initial compromise. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users should update Google Chrome on Mac to version 149.0.7827.155 or later, where this vulnerability is fixed. The vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_01750511403.html confirms the availability of this update. Applying this official fix mitigates the risk of sandbox escape via this vulnerability.
