Advisory
Source description from Wordfence Intelligence, credited to Karl Emil Nikka.
The FluentCRM - Marketing Automation For WordPress plugin for WordPress is vulnerable to unauthorized modification of data in versions up to, and including, 2.8.01 due to the use of an MD5 hash without a salt to control subscriptions.
