CVE-2026-0261: PAN-OS: Authenticated Admin Command Injection Vulnerability

MediumCVSS 6.1 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 24/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 1.4% (FIRST EPSS); higher than 72.9% 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-h36, 10.2.13-h21, 10.2.16-h7.

Low priority for now. Upgrade to Palo Alto Networks PAN-OS 10.2.10-h36, 10.2.13-h21, 10.2.16-h7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Multiple command injection vulnerabilities in Palo Alto Networks PAN-OS® software enable 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 impacted by these vulnerabilities.
