At a glance
CVE-2024-8349 is a high-severity Missing Authorization vulnerability in the Uncanny Groups for LearnDash WordPress plugin, affecting versions <= 6.1.0.1. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). 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 privilege escalation in all versions up to, and including, 6.1.0.1. This is due to the plugin not properly restricting what users a group leader can edit. This makes it possible for authenticated attackers, with group leader-level access and above, to change admin account email addresses which can subsequently lead to admin account access.
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 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.
