At a glance

CVE-2026-85569 is a medium-severity Improper Authorization vulnerability in the Tutor LMS WordPress plugin, affecting versions <= 4.0.7. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The issue is fixed in version 4.0.8; sites on affected versions should update now. Disclosed September 2026, reported by Charles Vosburgh.

Vulnerability Overview

The Tutor LMS plugin for WordPress is vulnerable to REST API request confusion in all versions 2.7.1 to 4.0.7. This makes it possible for attackers to initiate rest requests that may bypass proper authorization.

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-285: Improper Authorization

Reaching this weakness in Tutor LMS <= 4.0.7 takes a caller who can reach the endpoint. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.

A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For Tutor LMS the fix is 4.0.8: builds <= 4.0.7 are affected, anything from 4.0.8 onward is not.

Remediation

Update to version 4.0.8, 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: Tutor LMS 4.0.8 closes this, and updating the plugin is the step that ends it.
