Standard-Update-Befehl
sudo /scripts/upcp --forceWas das unter einer SharedLicense-Lizenz bedeutet
Your SharedLicense license itself is not affected — this is a vulnerability in cPanel software, not in licensing. Licenses continue to work during and after the update; there is no need to re-issue or re-activate anything. If you resell cPanel under your own brand, patch client servers too — unpatched installs put your reputation at risk, not your license.
Situation
An authenticated cPanel account holder with mail-related privileges can create arbitrary files on the server through cPanel’s EmailTrack functionality.
