Inappropriate implementation in Updater in Google Chrome on Windows prior to 151.0.7922.72 allowed a local attacker to perform UI spoofing via a malicious file. (Chromium security severity: Low)

AnalysisAI

UI spoofing in the Google Chrome Updater component on Windows (prior to 151.0.7922.72) enables a local attacker to present a falsified interface to users by placing a malicious file in a location the Updater processes. Chromium's own team rates this 'Low' severity, consistent with the 4.0 CVSS score, EPSS of 0.10% (1st percentile), and SSVC exploitation status of 'none'. No public exploit exists at time of analysis, and a vendor-confirmed patch is available in Chrome 151.0.7922.72.

Technical ContextAI

The affected component is the Google Chrome Updater (Google's Omaha update agent) running on Windows, identified via CPE cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*. CWE-451 (UI Misrepresentation of Critical Information) describes the root cause class: the implementation fails to sufficiently validate or isolate file inputs that influence how update-related UI is rendered or displayed, allowing an adversary-controlled file to alter what the user sees during an update interaction. This class of flaw is distinct from code execution or privilege escalation - the primary damage is deceiving the user rather than directly compromising system state, making it a social-engineering enabler rather than a direct exploit primitive.

RemediationAI

Upgrade Google Chrome for Windows to version 151.0.7922.72 or later; this is confirmed as the vendor-released patch per the Chrome stable channel advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. Chrome's auto-update mechanism will deliver this patch to most consumer endpoints without manual intervention, so the primary action for enterprise administrators is to verify that managed deployments have reached 151.0.7922.72 or higher via group policy reporting or endpoint management tooling. As a compensating control where immediate patching is delayed, restricting local write access to directories accessed by the Chrome Updater process can reduce exposure - note that this may also interfere with legitimate update processes. No workaround fully eliminates the risk without the patch.
