At a glance

CVE-2024-39642 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the LearnPress WordPress plugin, affecting versions <= 4.2.6.8.2. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above.

Vulnerability Overview

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.2.6.8.2 due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to perform an unauthorized action.

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 LearnPress <= 4.2.6.8.2 takes an account at Subscriber level or above. 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 LearnPress the fix is 4.2.6.9: builds <= 4.2.6.8.2 are affected, anything from 4.2.6.9 onward is not.

Remediation

Update to version 4.2.6.9, 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: LearnPress 4.2.6.9 closes this, and updating the plugin is the step that ends it.
