WordPress Tooltips <= 8.2.5 - Multiple Cross-Site Request Forgery

The WordPress Tooltips plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 8.2.5. This is due to missing or incorrect nonce validation on the 'show_member_user_roles' and 'memberdirectoryrolesetting' functions. This makes it possible for unauthenticated attackers to modify which user roles are added to the plugin's member directory via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
