A privilege escalation vulnerability in Google Chrome's DevTools allows attackers to exploit malicious extensions, posing a significant risk to browser security.

This vulnerability involves insufficient policy enforcement within the DevTools component. An attacker can exploit this by convincing a user to install a malicious Chrome extension, which then allows the attacker to escalate privileges within the browser environment.

With a CVSS score of 8.8, this vulnerability highlights the danger of extension-based attacks. Successful exploitation enables an attacker to gain elevated control over the browser, potentially accessing sensitive data, stored credentials, or performing actions on behalf of the user, leading to significant organizational risk.

Immediate Action: Update Google Chrome to version 149.0.7827.53/54 for Windows and macOS, or 149.0.7827.53 for Linux, immediately.

Proactive Monitoring: Audit installed browser extensions and restrict user ability to install unauthorized extensions through Group Policy or MDM.

Compensating Controls: Implement a strict allow-list for browser extensions and educate users on the risks associated with installing untrusted third-party add-ons.

Public Exploit Available: False

Administrators should enforce strict browser extension policies to minimize the attack surface. Updating to the latest stable version of Chrome is essential to patch the policy enforcement gap and prevent privilege escalation via malicious extensions.
