DescriptionCVE.org

Inappropriate implementation in Safebrowsing in Google Chrome on Mac prior to 151.0.7922.72 allowed a remote attacker to execute arbitrary code via a malicious file. (Chromium security severity: Low)

AnalysisAI

Remote code execution in Google Chrome on macOS prior to 151.0.7922.72 stems from an inappropriate implementation in the Safe Browsing component, where a remote attacker can trigger arbitrary code execution by luring a victim into opening or downloading a malicious file. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R) requires no privileges but does require user interaction, and Google has shipped a fixed Stable channel build. Despite the 8.8 CVSS, Chromium rated the underlying issue Low severity, EPSS is only 0.20% (10th percentile), and there is no public exploit identified at time of analysis.

Technical ContextAI

The flaw resides in Chrome's Safe Browsing subsystem - the Google service that inspects downloaded files and visited URLs against reputation lists to warn users of malware and phishing. An 'inappropriate implementation' here means the feature's file-handling logic behaves in a way that a malicious file can subvert to reach a code-execution path. The vulnerability is filed under CWE-269 (Improper Privilege Management), and the tags (RCE, Privilege Escalation) suggest the malicious file leverages a privilege/trust boundary weakness in how Safe Browsing processes it. The affected platform is specifically the macOS build of Chrome (CPE cpe:2.3:a:google:chrome), so the identical Windows/Linux binaries are not necessarily impacted the same way.

RemediationAI

Vendor-released patch: 151.0.7922.72 - update Google Chrome on macOS to 151.0.7922.72 or later via Chrome's built-in updater (chrome://settings/help) and relaunch the browser to apply it, per Google's Stable channel advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. In managed fleets, push the updated build through MDM/enterprise policy and force a relaunch to ensure the patched binary is active. As an interim compensating control before updating, advise users not to open or download untrusted files and, where policy allows, restrict downloads from untrusted sites; note this does not remove the flaw and reduces usability. Since Safe Browsing is the affected component, disabling it is counterproductive - it would remove other protections without reliably closing this path - so upgrading is strongly preferred over any toggle-based workaround.
