Urgent Security Brief: GlobeTier Infrastructure Hardened & Fully Patched

At GlobeTier, your infrastructure's security is our absolute priority. We are writing to inform you of two major global security vulnerabilities that were identified this week affecting cPanel/WHM and the Linux Kernel (CloudLinux).

Our technical team has been working around the clock to secure our network. Below is a detailed summary of the situation and the actions taken.

1. Managed Services (Shared Hosting, Reseller, & Managed VPS)

Status: SECURED If your services are managed by GlobeTier, no action is required from your side.

• cPanel Patch: We have already force-updated all control panels to the secure versions (including 11.134.0.20).

• Kernel Hardening: We have implemented the official mitigations for the "Copy Fail" kernel exploit (CVE-2026-31431) across our entire fleet.

2. Unmanaged Services (Self-Managed VPS & Dedicated)

Status: ACTION REQUIRED If you manage your own server, you must manually apply these critical security updates immediately to prevent unauthorized access or privilege escalation.

Step A: Patching cPanel

Log in to your server via SSH as root and execute:

/scripts/upcp --force

Verified Secure Versions: Ensure your version is one of the following (or higher): 11.110.0.97 | 11.118.0.63 | 11.126.0.54 | 11.132.0.29 | 11.136.0.5 | 11.134.0.20

Step B: Patching Linux Kernel (Copy Fail)

For servers running CloudLinux 8, 9, or 10, apply the mandatory mitigation to disable the vulnerable component:

grubby --update-kernel=ALL --args="initcall_blacklist=algif_aead_init"
reboot

Note: A server reboot is required for this change to take effect.

Important Note on EOL Systems

If your server is running an unsupported or End-of-Life (EOL) version of cPanel or OS, it will not receive these patches. We strongly urge you to migrate to a supported version immediately.
