At a glance

CVE-2026-92715 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the Tutor LMS WordPress plugin, affecting versions <= 4.1.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 4.1.1; sites on affected versions should update now. Disclosed October 2026, reported by owlmind.

Vulnerability Overview

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.0 via the 'ID' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with author-level access and above, to modify arbitrary courses created by other instructors — overwriting their title, content, and status — and reassign ownership of those courses to themselves. This is possible because Input::sanitize_array() preserves attacker-supplied POST keys (including 'ID') without stripping them, and WordPress interprets a non-empty ID in the wp_insert_post() argument array as an update to the existing post rather than a new insert.

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-639: Authorization Bypass Through User-Controlled Key

Tutor LMS <= 4.1.0 carries this weakness at sanitize_array(), and reaching it takes an account at Author level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Tutor LMS the fix is 4.1.1: builds <= 4.1.0 are affected, anything from 4.1.1 onward is not.

Remediation

Update to version 4.1.1, 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: Tutor LMS 4.1.1 closes this, and updating the plugin is the step that ends it.
