Palo Alto Networks Globalprotect vulnerabilities

CVE-2026-0299 High · 7.8 CWE-426 Aug 13, 2026

GlobalProtect App: Local Privilege Escalation Vulnerabilities

Local privilege escalation vulnerabilities in the Palo Alto Networks GlobalProtect™ app enable 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, and Chrome OS is not affected.

CVE-2026-0298 High · 8.1 CWE-94 Aug 13, 2026

GlobalProtect App: Code Execution Vulnerability in Windows Pre-Logon Access Provider (PLAP)

An improper input validation vulnerability exists in the Windows Pre-Logon Access Provider (PLAP) component of the Palo Alto Networks GlobalProtect™ app on Windows devices which enables a man-in-the-middle (MitM) attacker to execute arbitrary code with SYSTEM privileges on an affected client. The GlobalProtect app on Linux, macOS, iOS, Android, and Chrome OS is not affected.

CVE-2026-0297 High · 8.1 CWE-787 Aug 13, 2026

GlobalProtect App: Buffer Overflow Vulnerability during UDP Tunnel Handshake

A buffer overflow vulnerability exists in the Palo Alto Networks GlobalProtect™ app that enables a man-in-the-middle (MitM) attacker or a rogue gateway to disrupt system processes and potentially execute arbitrary code with elevated privileges (SYSTEM privileges on Windows, and root privileges on macOS and Linux).

CVE-2026-0296 High · 7.4 CWE-295 Aug 13, 2026

GlobalProtect App: Improper Certificate Validation Bypass Vulnerability

Improper certificate validation vulnerabilities in Palo Alto Networks GlobalProtect™ app enable an unauthenticated attacker with man-in-the-middle (MitM) access to intercept and modify application communications. VPN tunnel traffic is not impacted. The GlobalProtect app on iOS, Android, and Chrome OS is not affected.

CVE-2026-0295 High · 7.0 CWE-362 Aug 13, 2026

GlobalProtect App: Local Privilege Escalation via Race Condition on macOS

A race condition in the Palo Alto Networks GlobalProtect™ client on macOS enables a locally authenticated low-privileged attacker to escalate their privileges to root. The GlobalProtect app on Linux, Windows, iOS, Android, and Chrome OS is not affected.

CVE-2026-0267 Medium · 5.5 CWE-532 Jun 10, 2026

GlobalProtect App: Information Exposure Vulnerability on macOS

An information exposure vulnerability in the Palo Alto Networks GlobalProtect app on macOS enables a local user to learn the configured passcodes for disabling, disconnecting, or uninstalling the GlobalProtect app. After the passcode is known, the user can perform these actions even if the GlobalProtect app configuration would not normally permit them to do so.

CVE-2026-0251 High · 7.8 CWE-426 May 13, 2026

GlobalProtect App: Local Privilege Escalation Vulnerabilities

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.

CVE-2026-0250 High · 8.1 CWE-787 May 13, 2026

GlobalProtect App: Buffer Overflow Vulnerability during connection to Portal or Gateway

A buffer overflow vulnerability exists in the Palo Alto Networks GlobalProtect™ app that enables a man in the middle attacker to disrupt system processes and potentially execute arbitrary code with SYSTEM privileges. This vulnerability is triggered during the processing of requests and responses exchanged between Portal and Gateway. The GlobalProtect app on iOS is not affected.

CVE-2026-0249 Medium · 6.5 CWE-295 May 13, 2026

GlobalProtect App: Certificate Validation Bypass Vulnerabilities

Multiple improper certificate validation vulnerabilities in the Palo Alto Networks GlobalProtect™ app enables an attacker to intercept encrypted communications and potentially compromise the endpoint. This can enable a local non-administrative operating system user or an attacker on the same subnet to redirect traffic to an unauthorized server and facilitate the installation of malicious software. The GlobalProtect app on Linux, Windows, iOS and GlobalProtect UWP app are not affected.
