At a glance
CVE-2025-3284 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the User Registration PRO WordPress plugin, affecting versions <= 5.1.3. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 5.2.0; sites on affected versions should update now. Disclosed April 2025, reported by wesley (wcraft).
Vulnerability Overview
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. This makes it possible for unauthenticated attackers to force delete users, including administrators, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
User Registration PRO <= 5.1.3 carries this weakness at user_registration_pro_delete_account(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For User Registration PRO the fix is 5.2.0: builds <= 5.1.3 are affected, anything from 5.2.0 onward is not.
Remediation
Update to version 5.2.0, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to User Registration PRO: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: User Registration PRO 5.2.0 closes this, and updating the plugin is the step that ends it.
