malicious browser extensions

Malicious browser extensions pose a growing security risk, particularly when they exploit vulnerabilities in browsers like Chrome. A recent thread discusses CVE-2026-7958, a medium-severity ServiceWorker flaw in Chrome 148 that could allow a malicious extension to inject arbitrary scripts or HTML after user installation. This highlights that extension governance is now a critical part of browser patch management for Windows administrators. The risk is not from drive-by exploits but from the browser failing to contain extensions the user has installed. Discussions on WindowsForum emphasize the need for strict policies to manage and audit browser extensions in enterprise environments.
