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

Noroxi assessment

Priority: Monitor (action score 24/100)

Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 1.3% (FIRST EPSS); higher than 71.1% of all records.
Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Palo Alto Networks PAN-OS 10.2.10-h37, 10.2.13-h22, 10.2.16-h8.

Low priority for now. Upgrade to Palo Alto Networks PAN-OS 10.2.10-h37, 10.2.13-h22, 10.2.16-h8 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
