What it changes for you

Nothing visible for you; companies must update their firewalls.

Nothing to do.
If you run a website or an app
Upgrade PAN-OS to the fixed release for your branch and restrict the management interface to trusted internal IP addresses. There is no full workaround. Cloud NGFW and Prisma Access are not affected.
