CVE-2026-0261: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Palo Alto Networks Cloud NGFW
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.

Technical Summary
This vulnerability involves multiple command injection issues in Palo Alto Networks PAN-OS software, enabling an authenticated administrator to bypass system restrictions and execute arbitrary OS commands with root privileges. Exploitation requires access to the PAN-OS CLI or Web UI. The vulnerability affects PA-Series and VM-Series firewalls and Panorama (virtual and M-Series) but does not impact Cloud NGFW or Prisma Access. The risk is mitigated by limiting CLI and management interface access to trusted administrators and internal IP addresses. No patch or official remediation level has been provided yet.
Potential Impact
An authenticated administrator with access to the PAN-OS CLI or Web UI can execute arbitrary commands as root, potentially leading to full system compromise. The vulnerability does not affect cloud-hosted services like Cloud NGFW or Prisma Access. The impact is significant but mitigated by access restrictions.
Mitigation Recommendations
No official patch or remediation has been announced. The vendor recommends minimizing risk by restricting CLI access to a limited group of administrators and limiting management web interface access to trusted internal IP addresses as per Palo Alto Networks' best practice deployment guidelines. Monitor the vendor advisory for updates on patches or fixes.
