What is CVE-2026-0296?

The vulnerability in Palo Alto Networks GlobalProtect app stems from improper certificate validation practices, which allow an unauthenticated attacker to execute man-in-the-middle (MitM) attacks. This enables the attacker to intercept and modify communications between the app and the server. However, it is important to note that no impact has been reported on VPN tunnel traffic, and certain platforms, including iOS, Android, and Chrome OS, remain unaffected. Proper measures should be taken to secure application communications to mitigate such threats.

Affected Version(s)

GlobalProtect App Linux 6.3.0 < 6.3.3-h15

GlobalProtect App Linux 6.2.0

GlobalProtect App Linux 6.0.0 < 6.0.15
