At a glance

CVE-2025-6680 is a medium-severity Improper Access Control vulnerability in the Tutor LMS WordPress plugin, affecting versions <= 3.8.3. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function.

Vulnerability Overview

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.8.3. This makes it possible for authenticated attackers, with tutor-level access and above, to view assignments for courses they don't teach which may contain sensitive information.

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-284: Improper Access Control

Reaching this weakness in Tutor LMS <= 3.8.3 takes a caller who can reach the endpoint. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For Tutor LMS the fix is 3.9.0: builds <= 3.8.3 are affected, anything from 3.9.0 onward is not.

Remediation

Update to version 3.9.0, 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 3.9.0 closes this, and updating the plugin is the step that ends it.
