We have updated our servers with the new CageFS security updates. They were recommended for the CloudLinux update as they fixed 2 importantant security vulnerabilities.
Changelog:

CAG-826: fixed a security issue in CageFS found by Patrick William from Rack911 Labs:
removed /root directory accessible for users inside CageFS. Files in that directory (if they exist) are accessible for user via ~/.cagefs/root only;
disabled an ability to execute proxyexec wrappers as root inside CageFS (crontab, sendmail, etc). Admin should enter to CageFS as a user to do so;
