What is CVE-2026-0261?

Multiple command injection vulnerabilities exist in Palo Alto Networks PAN-OS software that can be exploited by an authenticated administrator. This can lead to unauthorized command execution as a root user. To mitigate this risk, it is crucial to limit CLI access to a trusted group of administrators and restrict access to the management web interface to secure internal IP addresses. This vulnerability is relevant for PAN-OS on PA-Series and VM-Series firewalls, as well as Panorama models. It's important to note that Cloud NGFW and Prisma Access services are not affected by these vulnerabilities.
