Our servers are not vulnerable to the April 2026 cPanel, “Copy Fail” or “Dirty Frag” security bugs

Posted April 29th, 2026 in Tech Corner. Tags: .

Customers have asked us whether our servers are vulnerable to the recent serious security bug in the cPanel software, and to CVE-2026-31431 (nicknamed “Copy Fail”) and “Dirty Frag”, in the Linux kernel. All of these bugs could allow ”hackers” to modify websites.

The good news is that your site on our servers is safe from all three. We don’t use cPanel branded software at all, and we don’t use a vulnerable versions of the kernel software on our servers. We’ve verified in multiple ways that our servers are not vulnerable to either problem.

(Edit May 8: Updated to include information about new “Dirty Frag” exploit.)
