CVE-2026-0298

SYSTEM code execution by man-in-the-middle attackers

Published Aug 13, 2026 · Updated Aug 13, 2026

Code injection in GlobalProtect App 6.0, 6.2, and 6.3 for Windows allows man-in-the-middle attackers to execute code as SYSTEM. Palo Alto Networks identifies improper input validation in the Windows PLAP component but has not disclosed the input, code locus, or validation failure that produces the injection. Exposure requires SAML authentication in Connect Before Logon, and successful exploitation grants SYSTEM-level control of the Windows client.
