SECURITY ISSUE INFORMATION

The cPanel security team identified the resolved security issues. There is no reason to believe that these vulnerabilities have been made known to the public. As such, cPanel will only release limited information about the vulnerabilities at this time.

Once sufficient time has passed, allowing cPanel & WHM systems to automatically update to the new versions, cPanel will release additional information about the nature of the security issues. This Targeted Security Release addresses 20 vulnerabilities in cPanel & WHM software versions 11.54, 11.52, 11.50, and 11.48.

Due to the severity of the issues addressed in this release, cPanel is extending the blackout period on additional information to a full week. Additional information is scheduled for release on January 25, 2016.
