At a glance

CVE-2025-32230 is a medium-severity Improper Input Validation vulnerability in the Tutor LMS WordPress plugin, affecting versions <= 3.4.0. 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 3.4.1; sites on affected versions should update now. Disclosed April 2025, reported by Revan Arifio.

Vulnerability Overview

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to HTML Injection in all versions up to, and including, 3.4.0. This is due to the plugin not properly restricting HTML content from subscribers. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject HTML where they should not be authorized to.

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-20: Improper Input Validation

Reaching this weakness in Tutor LMS <= 3.4.0 takes an account at Subscriber level or above. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.

The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. For Tutor LMS the fix is 3.4.1: builds <= 3.4.0 are affected, anything from 3.4.1 onward is not.

Remediation

Update to version 3.4.1, or a newer patched version

How does WordSec protect against this?

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Tutor LMS 3.4.1 closes this, and updating the plugin is the step that ends it.
