CVE-2026-0300Unauthenticated RCE in Palo Alto PAN-OS User-ID Authentication Portal (Captive Portal)In the wildEvidence1

Palo Alto Networks believes the in-the-wild exploitation of a zero-day vulnerability (CVE-2026-0300) in its firewalls is likely the work of state-sponsored threat actors. CVE-2026-0300 is a buffer overflow vulnerability in the User-ID Authentication Portal service of Palo Alto Networks PAN-OS software, and can be exploited by unauthenticated attackers sending specially crafted packets to internet-facing User-ID Authentication Portals.
