At a glance

CVE-2024-8123 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the WP Extended WordPress plugin, affecting versions <= 3.0.8. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). The issue is fixed in version 3.0.9; sites on affected versions should update now. Disclosed September 2024, reported by Marco Wotschka.

Vulnerability Overview

The The Ultimate WordPress Toolkit – WP Extended plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.0.8 via the duplicate_post function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Contributor-level access and above, to duplicate posts written by other authors including admins. This includes the ability to duplicate password-protected posts, which reveals their contents.

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 WP Extended <= 3.0.8 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 WP Extended the fix is 3.0.9: builds <= 3.0.8 are affected, anything from 3.0.9 onward is not.

Remediation

Update to version 3.0.9, 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: WP Extended 3.0.9 closes this, and updating the plugin is the step that ends it.
