At a glance

CVE-2024-6366 is a medium-severity Missing Authorization vulnerability in the User Profile Builder WordPress plugin, affecting versions <= 3.11.7. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.11.8; sites on affected versions should update now. Disclosed July 2024, reported by Michel Prunet.

Vulnerability Overview

The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to unauthorized file uplloads due to a missing capability check on the wppb_upload_file_type() function in all versions up to, and including, 3.11.7. This makes it possible for unauthenticated attackers to upload arbitrary media files via the async upload functionality.

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-862: Missing Authorization

User Profile Builder <= 3.11.7 carries this weakness at wppb_upload_file_type(), and reaching it takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For User Profile Builder the fix is 3.11.8: builds <= 3.11.7 are affected, anything from 3.11.8 onward is not.

Remediation

Update to version 3.11.8, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: User Profile Builder 3.11.8 closes this, and updating the plugin is the step that ends it.
