High severity, CVSS 7.1. EPSS: 0.3% chance of exploitation in the next 30 days.

A vulnerability in the GlobalProtect portal in Palo Alto Networks PAN-OS software enables a malicious authenticated GlobalProtect user to impersonate another GlobalProtect user. Active GlobalProtect users impersonated by an attacker who is exploiting this vulnerability are disconnected from GlobalProtect. Upon exploitation, PAN-OS logs indicate that the impersonated user authenticated to GlobalProtect, which hides the identity of the attacker.
