Security Rating
cPanel has assigned this vulnerability a CVSSv3 score of 2.7 CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L
Description
Previously, when you converted an addon domain to a normal account, it was not required that a reseller specify a package for the account creation. This allowed the reseller to use the system’s “default” package that has no account limits. Now, an addon domain conversion requires that a reseller have and specify a valid package for the account.
