At a glance

CVE-2024-0872 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the Watu Quiz WordPress plugin, affecting versions <= 3.4.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The issue is fixed in version 3.4.1.1; sites on affected versions should update now. Disclosed April 2024, reported by Lucio Sá.

Vulnerability Overview

The Watu Quiz plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.4.1 via the watu-userinfo shortcode. This makes it possible for authenticated attackers, with contributor-level access and above, to extract sensitive user meta data which can include session tokens and user emails.

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 interaction from a victim user.

CWE-639: Authorization Bypass Through User-Controlled Key

Reaching this weakness in Watu Quiz <= 3.4.1 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 Watu Quiz the fix is 3.4.1.1: builds <= 3.4.1 are affected, anything from 3.4.1.1 onward is not.

Remediation

Update to version 3.4.1.1, 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: Watu Quiz 3.4.1.1 closes this, and updating the plugin is the step that ends it.
