We have completed security updates for CloudLinux and PHP across our servers in response to the recently discovered PHP vulnerability.

All PHP versions from 7.4 to 8.5 have now been patched on our servers. In addition, we use Imunify360, which provides an extra layer of protection against attacks attempting to exploit the vulnerability.

We continuously monitor security updates from CloudLinux and other software vendors and install relevant updates to keep our hosting environment secure.

We Recommend Updating Your PHP Version

Although the necessary security patches have been installed, we recommend that all customers use a newer, actively supported PHP version.

We particularly encourage customers still using PHP 7.0, 7.1, 7.2, or 7.3 to upgrade to a newer PHP version as soon as possible. These older versions no longer receive regular security updates from the official PHP project and may therefore pose an increased security risk.

Before upgrading your PHP version, we recommend checking that your website, plugins, and other applications are compatible with the new version.

We Continue to Monitor the Situation

New security patches are continuously being released by various software vendors. We are closely monitoring developments and will continue updating our servers as relevant updates become available.

Our customers do not need to take any further action regarding server-level security updates. However, we strongly recommend keeping your website, CMS, plugins, and PHP version up to date.

The new CloudLinux security updates do not introduce new PHP version numbers. You can find details about the patched versions here:
