At a glance

CVE-2022-2034 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Sensei LMS WordPress plugin, affecting versions <= 4.4.3. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 4.5.0; sites on affected versions should update now. Disclosed August 2022, reported by Veshraj Ghimire.

Vulnerability Overview

The Sensei LMS plugin for WordPress is vulnerable to Sensitive Data Exposure in versions up to, and including, 4.4.3. This is due to missing permission checks on one of its REST endpoints and allows unauthenticated attackers to extract sensitive data including private messages sent to teachers.

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 privileges on the target site, and no interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Sensei LMS <= 4.4.3 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Sensei LMS the fix is 4.5.0: builds <= 4.4.3 are affected, anything from 4.5.0 onward is not.

Remediation

Update to version 4.5.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Sensei LMS 4.5.0 closes this, and updating the plugin is the step that ends it.
