Multiple improper certificate validation vulnerabilities in the Palo Alto Networks GlobalProtect™ app enables an attacker to intercept encrypted communications and potentially compromise the endpoint. This can enable a local non-administrative operating system user or an attacker on the same subnet to redirect traffic to an unauthorized server and facilitate the installation of malicious software.

The GlobalProtect app on Linux, Windows, iOS and GlobalProtect UWP app are not affected.
