Official Description
Multiple local privilege escalation vulnerabilities in the Palo Alto Networks GlobalProtect™ app allow a local user to escalate their privileges to NT AUTHORITY\SYSTEM on Windows and root on macOS and Linux. This enables a non-administrative user to execute arbitrary commands with administrative privileges.
The GlobalProtect app on iOS, Android, Chrome OS and GlobalProtect UWP app are not affected.
Technical Analysis
CVE-2026-0251 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
