  We have completed applying the security update across our hosting fleet to servers which we are able to access and patch but there still remains a subset of servers that we were unable to patch. This is partly due to End of Life software, e.g. cPanel on CentOS 6. Customers whose servers we were unable to patch should review their servers and ensure that their servers are running one of the following patched versions of cPanel: v11.110.0.143 v11.134.0.55 v11.136.0.39 v11.138.0.4 WP2: v11.138.1.9 Any version of cPanel which is not running one of these versions is vulnerable and should be updated. cPanel can be updated by using the following steps: https://docs.cpanel.net/whm/cpanel/upgrade-to-latest-version/ For the customers on CentOS 6 (or older) we strongly suggest migrating to an Alma 9 server in order to receive future security patches
