Affected: All managed cPanel & WHM servers
We have received advanced information of another patch that is expected to be released at around 5 am PST today.
Beginning immediately once the patch is made available, we will roll out this update across all servers under our management using the same progressive approach as yesterday.
Expected impact: Individual servers may experience a brief service interruption of under 5 minutes during their respective patch window. Services will resume automatically.
Managed clients (including Elastic Hosting and Reseller Hosting): No action required. The patch will be applied automatically.
Unmanaged clients running cPanel & WHM: Please apply this update as soon as possible. If you applied yesterday's patch, you must also apply this one. Refer to cPanel's support article for instructions on updating to a patched version.
We will update this post as the rollout progresses and confirm once all servers have been patched.
