What the vulnerability does
01Description
The User Registration & Membership – Custom Registration Form, Login Form, and User Profile plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.1.3. This is due to missing or incorrect nonce validation on the user_registration_pro_delete_account() function.
