PAN OS version 11.1.13-h1 is remediate or not?

S.Alizada — Mon, 26 Jan 2026 03:45:40 GMT

Dear all,

I have this questions where I want to make sure first before doing an upgrade on my PA-820?

Recently I have gone through the customer advisory of the following: (Customer Advisory on Device Certificate Renewal for NGFW Devices in Active-Passive High Availability (HA) with Service Route) and the CVE of the following (CVE-2026-0227 PAN-OS: Firewall Denial of Service (DoS) in GlobalProtect Gateway and Portal).

Now my PA-820 is configured with Service Route, but I want to make sure that I do the best practices and avoid any upcoming issues possible.

Through the Customer advisory it requires to upgrade the PAN-OS to 11.1.12.

while through the CVE it mentioned that PAN-OS versions 11.1.11 to 11.1.12 should be upgraded to 11.1.13 or later (11.1.13-h1).

Now my questions is that: Is PAN-OS version 11.1.13 or later remediated from the issues discussed in Customer Advisory and is it oke to upgrade to the version and fix the issues?

I would really appreciate urgent replies.

Thank you all.

Palo TAC preferred version is currently 11.1.13.

So I would go either with 11.1.13 or 11.1.13-h1.

11.1.13-h1 is preferred version plus some hotfixes. What exactly and if any of fixes affect your environment, you can see in release notes.
