CVE-2026-0315 in GlobalProtect App
Summary
by MITRE • 10/15/2026
A local privilege escalation vulnerability in the Palo Alto Networks GlobalProtect™ app enables a local user to escalate their privileges to root on macOS. This enables a non-administrative user to execute arbitrary commands with administrative privileges.
The GlobalProtect app on Linux, Windows, iOS, Android and Chrome OS is not affected by this vulnerability.

A critical local privilege escalation vulnerability has been identified within the Palo Alto Networks GlobalProtect application for macOS, allowing unprivileged users to gain root-level access to the system. This flaw specifically impacts the macOS implementation of the client software, while versions running on Linux, Windows, iOS, Android, and Chrome OS remain unaffected by this specific issue. The core technical deficiency lies in how the application handles file permissions or execution contexts during its installation or update processes, creating a pathway for local users to bypass standard operating system security controls. By exploiting this misconfiguration, an attacker who has already gained physical access or basic user-level credentials on the target macOS device can execute arbitrary commands with administrative privileges, effectively taking full control of the compromised machine.
From a technical perspective, this vulnerability aligns closely with CWE-269, which describes Improper Privilege Management, and more specifically CWE-732, concerning Incorrect Permission Assignment for Critical Resource. The flaw likely stems from insecure file system permissions or an improper use of setuid bits during the application's initialization or update routines. When a non-administrative user interacts with specific components of the GlobalProtect app, they can trigger actions that are executed by higher-privileged processes without adequate verification of their own authority. This breakdown in access control allows the attacker to inject malicious code into privileged execution contexts, leading to complete system compromise. The absence of these issues on other platforms suggests a platform-specific implementation error rather than a fundamental flaw in the GlobalProtect protocol or architecture itself.
The operational impact of this vulnerability is severe for organizations relying on macOS endpoints within their secure perimeter. Since Palo Alto Networks GlobalProtect is widely deployed as a VPN client to facilitate remote access, many corporate devices will have this software installed. An attacker with local access could leverage this privilege escalation to install persistent backdoors, exfiltrate sensitive data protected by endpoint security solutions, or pivot further into the internal network using valid administrative credentials obtained from the compromised host. This effectively neutralizes the security benefits provided by the VPN client and any associated endpoint protection agents that rely on standard user-level execution for integrity checks. The ability to execute arbitrary commands as root means that traditional detection mechanisms may fail to identify malicious activity if it is masked under legitimate system processes or administrative tools.
To mitigate this risk, organizations should immediately apply the latest security patches released by Palo Alto Networks for their GlobalProtect macOS clients. It is crucial to verify that all endpoints are running a version of the software where this permission issue has been resolved through code hardening and stricter adherence to least-privilege principles. In environments where patching cannot be performed instantly, administrators should consider restricting local user privileges or implementing application control policies to prevent unauthorized modifications to GlobalProtect binaries. Additionally, monitoring for unusual privilege escalation events or unexpected changes in file permissions within the GlobalProtect installation directory can help detect exploitation attempts. Regular audits of installed software and enforcement of strict macOS security configurations such as System Integrity Protection (SIP) will further reduce the attack surface associated with this vulnerability.
