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 10 vulnerabilities in cPanel & WHM software versions 88, 86, and 78.

Additional information is scheduled for release on May 19, 2020.
