serious security vulnerabilities

Hello, we have received a message from our hoster. “You are using the Advanced Contact form 7 DB plugin on your WordPress installation.
We have found various serious security gaps in this plugin.
Since the manufacturer of the plugin does not offer an update, this gap cannot be closed and thus jeopardizes the operation of your website. Please remove this plugin and/or replace it with another one.
Detailed information about the vulnerabilities can be found here: https://wpscan.com/vulnerability/eeaed3f8-42ac-40e0-a0fa-3c90eed527a4.” What can we do about it now?
Best regards Melanie
