CVE-2026-0249: CWE-295 Improper Certificate Validation in Palo Alto Networks GlobalProtect App
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.
AI Analysis
Technical Summary
This vulnerability, identified as CWE-295 (Improper Certificate Validation), affects Palo Alto Networks GlobalProtect app versions 6.2.0 and 6.3.0. It allows an attacker with local or network proximity to intercept and redirect encrypted traffic by exploiting flaws in certificate validation. The flaw could enable traffic redirection to unauthorized servers and facilitate malicious software installation. The issue is limited to specific versions of the GlobalProtect app and does not impact Linux, Windows, iOS, or UWP versions. No vendor advisory or patch information is currently available.
Potential Impact
An attacker on the same subnet or a local non-administrative user could exploit this vulnerability to intercept encrypted communications and redirect traffic to unauthorized servers. This could lead to the compromise of the endpoint through the installation of malicious software. The impact is limited to affected versions of the GlobalProtect app and does not extend to other platforms or versions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider avoiding the affected versions 6.2.0 and 6.3.0 of the GlobalProtect app or restrict network access to trusted environments to reduce exposure. Monitor Palo Alto Networks advisories for updates on patches or mitigations.
