browserextensionsecurity

The browserextensionsecurity tag covers discussions about security risks posed by browser extensions, particularly in Chromium-based browsers like Chrome and Edge. Topics include vulnerabilities such as CVE-2026-8006, a low-severity DevTools UI spoofing flaw, and CVE-2026-5904, a use-after-free in V8 reachable via malicious extensions. The tag also addresses the Cookie-Bite attack, which demonstrates how extensions can steal session cookies from Microsoft Entra ID, bypassing MFA. These threads emphasize that browser extensions are a growing enterprise attack surface, requiring careful management and patching on Windows systems.
