GlobalProtect App: Improper Control of Generation of Code

Published Updated By the CyberSecBulletin desk

CVE-2026-0298 is a high-severity improper control of generation of code vulnerability in GlobalProtect App from Palo Alto Networks, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 6.3.3-h14, 6.2.8-h13, 6.0.15 as the first without the flaw, so updating GlobalProtect App to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.66% chance of exploitation within 30 days, higher than 52% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update GlobalProtect App to 6.3.3-h14 or 6.2.8-h13 or 6.0.15, whichever matches your release line, or a later version.
  2. Update Globalprotect to 6.0.15 or 6.2.8 or 6.3.3, whichever matches your release line, or a later version.
  3. Read the advisory on security.paloaltonetworks.com for workarounds and exact fixed builds.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

An improper input validation vulnerability exists in the Windows Pre-Logon Access Provider (PLAP) component of the Palo Alto Networks GlobalProtect™ app on Windows devices which enables a man-in-the-middle (MitM) attacker to execute arbitrary code with SYSTEM privileges on an affected client. The GlobalProtect app on Linux, macOS, iOS, Android, and Chrome OS is not affected.

The underlying weakness: Improper Control of Generation of Code

The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

How developers prevent this class of flaw

  • Refactor your program so that you do not have to dynamically generate code.
  • Run your code in a jail or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product. Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection. This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise. Be careful to avoid CWE-243 and other weaknesses related to jails.
  • Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.
