At a glance

CVE-2023-47669 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the User Profile Builder WordPress plugin, affecting versions <= 3.10.3. It carries a CVSS score of 7.1 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication. The issue is fixed in version 3.10.4; sites on affected versions should update now. Disclosed November 2023, reported by Brandon James Roldan (tomorrowisnew).

Vulnerability Overview

The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.10.3. This is due to missing or incorrect nonce validation on the wppb_activate_pms_plugin and wppb_deactivate_pms_plugin functions. This makes it possible for unauthenticated attackers to activate and deactivate arbitrary plugins 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. A successful exploit has high impact on integrity.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in User Profile Builder <= 3.10.3 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 Profile Builder the fix is 3.10.4: builds <= 3.10.3 are affected, anything from 3.10.4 onward is not.

Remediation

Update to version 3.10.4, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to User Profile Builder: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: User Profile Builder 3.10.4 closes this, and updating the plugin is the step that ends it.
