PAN-OS: Authenticated Admin Command Injection Vulnerability

Plan PatchCVSS 8.6CVE-2026-0261May 13, 2026
Palo Alto Networks
IT in OT - Palo Alto firewalls are commonly deployed at IT/OT network boundaries
Summary

Multiple command injection vulnerabilities in Palo Alto Networks PAN-OS and Prisma Access allow an authenticated administrator to bypass system restrictions and execute arbitrary commands as root. The vulnerability requires the user to have access to the PAN-OS CLI or Web UI. Affected products include PAN-OS on PA-Series and VM-Series firewalls and Panorama appliances. Cloud NGFW and Prisma Access cloud services are not affected. Risk is significantly reduced when CLI access is restricted to a limited group of administrators and management access is limited to trusted internal IP addresses.

What this means
What could happen
An authenticated administrator with access to the PAN-OS command line or web interface could run arbitrary commands as root on the firewall, potentially allowing them to disable security features, alter firewall rules, or disrupt network operations.
Who's at risk
This affects network administrators and security teams managing Palo Alto Networks firewalls (PA-Series, VM-Series, and Panorama appliances) in any organization. If you run PAN-OS or Prisma Access on firewalls, you should review your administrator access controls and patch status.
How it could be exploited
An attacker with valid administrator credentials and network access to the firewall's management interface (CLI or Web UI) can inject commands that bypass system restrictions and execute arbitrary code with root privileges. This requires the attacker to already have authenticated access—there is no pre-authentication exploit path.
Prerequisites
  • Valid administrator credentials for PAN-OS CLI or Web UI
  • Network access to the management interface (port 443 for Web UI or SSH port for CLI)
