At a glance
CVE-2024-8350 is a low-severity Missing Authorization vulnerability in the Uncanny Groups for LearnDash WordPress plugin, affecting versions <= 6.1.0.1. It carries a CVSS score of 2.7 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Group Leader level or above. The issue is fixed in version 6.1.1; sites on affected versions should update now. Disclosed September 2024, reported by Karl Emil Nikka.
Vulnerability Overview
The Uncanny Groups for LearnDash plugin for WordPress is vulnerable to user group add due to a missing capability check on the /wp-json/ulgm_management/v1/add_user/ REST API endpoint in all versions up to, and including, 6.1.0.1. This makes it possible for authenticated attackers, with group leader-level access and above, to add users to their group which ultimately allows them to leverage CVE-2024-8349 and gain admin access to the site.
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-862: Missing Authorization
Reaching this weakness in Uncanny Groups for LearnDash <= 6.1.0.1 takes an account at Group Leader 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 Uncanny Groups for LearnDash the fix is 6.1.1: builds <= 6.1.0.1 are affected, anything from 6.1.1 onward is not.
Remediation
Update to version 6.1.1, 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: Uncanny Groups for LearnDash 6.1.1 closes this, and updating the plugin is the step that ends it.
