CVE-2025-0131: Opswat Metadefender Endpoint Security SDK

High severity, CVSS 7.1. EPSS: 0.2% chance of exploitation in the next 30 days.

An incorrect privilege management vulnerability in the OPSWAT MetaDefender Endpoint Security SDK used by the Palo Alto Networks GlobalProtect™ app on Windows devices allows a locally authenticated non-administrative Windows user to escalate their privileges to NT AUTHORITY\SYSTEM. However, execution requires that the local user also successfully exploits a race condition, which makes this vulnerability difficult to exploit.

Affected products

• Opswat Metadefender Endpoint Security SDK: from 4.3.0, before 4.3.4451 (fixed in 4.3.4451)
