Local Privilege Escalation Vulnerability in Palo Alto Networks GlobalProtect App

CVE-2026-0251

What is CVE-2026-0251?

CVE-2026-0251 is a local privilege escalation vulnerability affecting the Palo Alto Networks GlobalProtect app, which is designed to provide secure access to organizational resources over the internet. This app is crucial for enabling remote work while maintaining data protection. The vulnerability allows local users to escalate their privileges to NT AUTHORITY\SYSTEM on Windows and to root on macOS and Linux systems, thereby granting them the capability to execute arbitrary commands with administrative privileges. Such an escalation can be detrimental to an organization, as it not only compromises the security of the affected systems but also can result in unauthorized access to critical data and network resources.

Potential impact of CVE-2026-0251

1. Unauthorized System Access: The vulnerability enables non-administrative users to gain administrative privileges, which can lead to unauthorized access to sensitive information and system functionalities.

2. Execution of Arbitrary Commands: With elevated privileges, attackers can execute arbitrary commands on the affected machines, which may result in data manipulation, theft, or destruction.

3. Network Compromise: The ability for a user to escalate privileges may allow further intrusions into secure areas of the network, paving the way for broader system compromises and potential data breaches within the organization.
