CVE-2026-0273PAN-OS: Authenticated Admin Command Injection Vulnerability via CLI or Web UI

Description

A command injection vulnerability in Palo Alto Networks PAN-OS® software enables an authenticated administrator to bypass system restrictions and run arbitrary commands as a root user. To be able to exploit this issue, the user must have access to the PAN-OS CLI or Web UI. The security risk posed by this issue is significantly minimized when CLI access is restricted to a limited group of administrators and by restricting access to the management web interface to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 . This issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series). Cloud NGFW and Prisma® Access are not affected by this vulnerability.

Workaround: The vast majority of firewalls already follow Palo Alto Networks' and industry best practices. However, if you have not done so already, we strongly recommend that you secure access to your management interface according to our best practice deployment guidelines (https://live.paloaltonetworks.com/t5/community-blogs/critical-recommendations-for-deployment-guides-how-to-secure-the/ba-p/464431). Specifically, you should restrict management interface access to only trusted internal IP addresses.
