AI-suggested

To mitigate CVE-2025-13631, organizations should immediately update Google Chrome on all Mac devices to version 143.0.7499.41 or later, where the vulnerability is patched. Beyond patching, organizations should implement strict controls on file downloads and email attachments, employing advanced threat protection solutions to detect and block crafted malicious files targeting the updater component. User awareness training should emphasize the risks of interacting with unsolicited files and links, reducing the likelihood of successful exploitation via social engineering. Network segmentation and endpoint detection and response (EDR) tools can help identify anomalous updater behavior indicative of exploitation attempts. Additionally, restricting the execution privileges of updater processes through macOS security features such as System Integrity Protection (SIP) and application sandboxing can limit the impact of potential exploits. Regular auditing of Chrome updater logs and monitoring for unusual privilege escalations will aid in early detection. Finally, organizations should maintain an up-to-date inventory of Mac devices and ensure compliance with patch management policies to reduce exposure.

Description

Inappropriate implementation in Google Updater in Google Chrome on Mac prior to 143.0.7499.41 allowed a remote attacker to perform privilege escalation via a crafted file. (Chromium security severity: High)
