Frequently Asked Questions
CVE-2026-0300: Palo Alto Networks PAN-OS Captive Portal Unauthenticated RCE
What is CVE-2026-0300 and why is it critical?
CVE-2026-0300 is a buffer overflow vulnerability in the User-ID Authentication Portal (Captive Portal) of Palo Alto Networks PAN-OS. It allows an unauthenticated, network-adjacent attacker to execute arbitrary code with root privileges by sending specially crafted packets. This vulnerability is actively exploited in the wild, targeting internet-exposed Authentication Portals. Immediate remediation is required due to confirmed exploit automation and active attacks. [Source]
Which PAN-OS versions are affected by CVE-2026-0300?
The affected versions are PAN-OS < 12.1.4-h5, < 11.2.4-h17, < 11.1.4-h33, and < 10.2.7-h34 on PA-Series and VM-Series firewalls with Captive Portal enabled. Cloud NGFW, Prisma Access, and Panorama are not affected. [Source]
