Cpanel recently announced a new vulnerability for their servers for the password reset option.
We'll show you how to turn off the password reset option for failed logins to Cpanel through Web Host Manager.
Description
The feature "Allow cPanel users to reset their password via email",
found in WebHostManager in the "Tweak Settings" section allows for a
cpanel user to run some commands as the root user.
It's strongly suggested that all Cpanel users disable this feature.
Affected Systems
All builds of Cpanel on all platforms are vulnerable up to and including (9.1.0
build 34), all builds after that have been fixed.

2. Click on Tweak Settings in the upper left hand corner.
