Access violation vulnerability in BM Content Builder 3.16.2.1

The BM Content Builder plugin for WordPress has a security issue that allows someone to change important information without permission. This could lead to someone gaining more power and control on a website. This issue affects all versions of the plugin, including the most recent one. This means that people who are logged in and have at least Subscriber level access can change certain settings on a WordPress site. This can be used to make themselves an administrator and allow them to register new users, giving them even more control.
