Is PAN-OS 11.1.4-h33 vulnerable?

Dear Community Members,

I want to ask couple of things:

Is the PAN OS 11.1.4-h33 vulnerable based on CVE-2026-0273 PAN-OS: Authenticated Admin Command Injection Vulnerability via CLI or Web UI and should be upgraded to PAN OS version 11.1.4-h34 and above?

For PA-14020 it came with a base of 11.1.0, can this support to move to other based PAN OS like 12.x.x or 10.x.x as an example, I have searched alot but couldn't find a proper source to confirm it.

Looking forward to hearing from you.

Thank you.

Best Regards,

Shah.

Hi @S.Alizada ,

Here's the security advisory:
https://security.paloaltonetworks.com/CVE-2026-0273

I'm guessing you mean the PA-1420 ?

If that's the case, it can NOT be downgraded to PAN-OS 10.x. PAN-OS 11.x is the absolute minimum for that hardware.

YES, you can upgrade to PAN-OS 12.x

Kind regards,
