Input validation vulnerability in User Registration PRO – Custom Registration Form, Login Form, and User Profile WordPress Plugin 5.1.3

A popular plugin for WordPress called “User Registration & Membership” has a security issue that could put websites at risk. The problem affects all versions up to version 5.1.3. Essentially, the plugin doesn’t properly check for a special code that helps prevent attacks. This means that someone who isn’t even logged in could trick a site administrator into accidentally deleting user accounts, even important ones like administrators.
