Palo Alto Networks Patches Actively Exploited PAN-OS RCE Flaw; CISA Adds It to KEV List

Summary
Palo Alto Networks issued updates for an authenticated PAN-OS management-interface RCE flaw after observing very limited exploitation. CISA added it and an actively exploited Cisco Secure Email Gateway flaw to its KEV catalog.
Key points
- CVE-2026-0322 is an authenticated remote code execution flaw in the PAN-OS management interface, allowing an attacker with network access to run code as root.
- The flaw affects PA-Series and VM-Series firewalls and Panorama; Cloud NGFW and Prisma Access are not affected.
- Palo Alto Networks issued security updates and advised restricting management-interface access to trusted internal IP addresses or a jump box.
- Palo Alto Networks reported “very limited exploitation” but gave no details about the activity, responsible actors, or when it began.
