Administrator-only CLI access drives PR:H and AV:N; arbitrary root execution independently warrants A:H despite vendor's conservative VA:N choice.

Lifecycle Timeline
3DescriptionCVE.org
A command injection vulnerability in the management plane of Palo Alto Networks PAN-OS® software enables an authenticated administrator to execute arbitrary OS commands as root.
The security risk posed by this issue is significantly minimized when CLI access is restricted to a limited group of administrators.
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 this vulnerability.
AnalysisAI
Command injection in the Palo Alto Networks PAN-OS management plane allows an authenticated administrator to execute arbitrary OS commands with root privileges on PA-Series, VM-Series, and Panorama appliances. The vulnerability is classified CWE-78 and is reachable via the network-accessible management interface, though the requirement for administrator-level credentials substantially constrains the attacker pool. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid, authenticated PAN-OS administrator account - unauthenticated users and low-privilege operator or read-only roles cannot trigger this vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 6.0 (Medium) accurately reflects the high privilege prerequisite (PR:H) that is the dominant risk-reducing factor - only authenticated administrators can reach the vulnerable surface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained PAN-OS administrator credentials - through phishing, credential stuffing, or insider access - connects to the management plane interface over the network and submits a crafted CLI command embedding OS shell metacharacters. The management plane passes the unsanitized input to the underlying OS shell, executing the injected payload with root privileges and granting full OS-level control of the appliance. … |
| Remediation | The primary remediation is to apply the vendor-released patch per the Palo Alto Networks advisory at https://security.paloaltonetworks.com/CVE-2026-0286 - exact fix versions are not present in the current data and must be confirmed from that advisory before deployment. … Detailed patch versions, workarounds, and compensating controls in full report. |
