Input validation vulnerability in User Registration & Membership – Custom Registration Form Builder, Custom Login Form, User Profile, Content Restriction & Membership Plugin 4.2.4

  • Severity: medium-risk
  • Status: Fixed
  • Publication: July 21, 2025

The User Registration plugin for WordPress has a security issue that allows attackers to inject harmful code into pages. This can happen because the plugin does not properly clean or protect the data entered by users. As a result, attackers who have contributor-level access or higher can add their own code to pages, which will run whenever someone visits that page.
