At a glance
CVE-2024-31341 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the User Profile Builder WordPress plugin, affecting versions <= 3.11.2. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview
The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to restricted email domain bypass in all versions up to, and including, 3.11.2. This makes it possible for unauthenticated attackers to register with emails that are restricted.
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, and no interaction from a victim user.
CWE-639: Authorization Bypass Through User-Controlled Key
Reaching this weakness in User Profile Builder <= 3.11.2 takes a caller who can reach the endpoint. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For User Profile Builder the fix is 3.11.3: builds <= 3.11.2 are affected, anything from 3.11.3 onward is not.
Remediation
Update to version 3.11.3, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: User Profile Builder 3.11.3 closes this, and updating the plugin is the step that ends it.
