At a glance

CVE-2026-12275 is a medium-severity Improper Authentication vulnerability in the Tutor LMS WordPress plugin, affecting versions <= 3.9.12. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 3.9.13; sites on affected versions should update now. Disclosed June 2026, reported by Dilovar Berdiev.

Vulnerability Overview

The Tutor LMS plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.9.12. This makes it possible for authenticated attackers, with Subscriber-level access and above, to enroll in unauthorized courses and private content.

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-287: Improper Authentication

Reaching this weakness in Tutor LMS <= 3.9.12 takes an account at Subscriber level or above. Improper authentication means the mechanism that proves who a caller is can be satisfied without the secret it was supposed to require.

An attacker authenticates as another user — administrators included — without ever knowing a password, so password policies and login rate limits never come into play. For Tutor LMS the fix is 3.9.13: builds <= 3.9.12 are affected, anything from 3.9.13 onward is not.

Remediation

Update to version 3.9.13, 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 3.9.13 closes this, and updating the plugin is the step that ends it.
