Critical Vulnerability Advisory: cPanel, Linux Kernel, Apache & OpenSSH Updates

We are sending this security notice to VPS and dedicated server customers regarding several recently disclosed vulnerabilities affecting common Linux hosting environments.

These issues may affect servers running cPanel/WHM, Apache HTTP Server, OpenSSH, CloudLinux, AlmaLinux, Rocky Linux, RHEL-compatible systems, Ubuntu, Debian, or other Linux distributions.

Some of these issues are confirmed as actively exploited, while others are high-impact vulnerabilities affecting common hosting components. We strongly recommend reviewing the details below and applying the applicable patches as soon as possible.

Important: If your VPS or dedicated server is unmanaged, you are responsible for reviewing, patching, rebooting, and verifying your own server. If your server is covered by our managed administration service, our team is reviewing applicable systems and applying vendor-supported updates where possible.
