CVE-2026-0322
Palo Alto Networks PAN-OS Code Injection Vulnerability
Published Oct 14, 2026 · corrected/updated Oct 15, 2026 · Palo Alto Networks PAN-OS · evidence confidence very high
A remote code execution (RCE) vulnerability in the management interface of Palo Alto Networks PAN-OS® software enables an authenticated attacker with network access to execute arbitrary code with root privileges on the firewall. The security risk posed by this issue is minimized by restricting access to the management 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 this vulnerability.
