User Registration – Custom Registration Form, Login Form, and User Profile WordPress Plugin
- Published on
- Sep 13, 2026
- Research Description
- The User Registration & Membership WordPress plugin before 5.2.8 does not check the capability of the user making a membership purchase, and does not validate the payment method or the plan submitted with it, allowing any authenticated user such as a subscriber to be granted the WordPress role attached to a paid plan without paying for it. Where the site owner has mapped a plan to a privileged role, this leads to privilege escalation up to administrator.
- Affected versions
-
max 5.2.8.
- Status
-
vulnerable
