At a glance

CVE-2024-10008 is a high-severity Missing Authorization vulnerability in the Masteriyo LMS WordPress plugin, affecting versions <= 1.13.3. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Student level or above. The issue is fixed in version 1.13.4; sites on affected versions should update now. Disclosed October 2024, reported by floerer.

Vulnerability Overview

The Masteriyo LMS – eLearning and Online Course Builder for WordPress plugin for WordPress is vulnerable to unauthorized user profile modification due to missing authorization checks on the /wp-json/masteriyo/v1/users/$id REST API endpoint in all versions up to, and including, 1.13.3. This makes it possible for authenticated attackers, with student-level access and above, to modify the roles of arbitrary users. As a result, attackers can escalate their privileges to the Administrator and demote existing administrators to students.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-862: Missing Authorization

Reaching this weakness in Masteriyo LMS <= 1.13.3 takes an account at Student level or above. 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 Masteriyo LMS the fix is 1.13.4: builds <= 1.13.3 are affected, anything from 1.13.4 onward is not.

Remediation

Update to version 1.13.4, 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: Masteriyo LMS 1.13.4 closes this, and updating the plugin is the step that ends it.
