At a glance

CVE-2026-5348 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the Academy LMS WordPress plugin, affecting versions <= 3.8.1. 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 3.8.2; sites on affected versions should update now. Disclosed July 2026, reported by Md. Moniruzzaman Prodhan (NomanProdhan).

Vulnerability Overview

The Academy LMS – WordPress LMS Plugin for Complete eLearning Solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.8.1. This is due to the '/topics' REST API endpoint being registered with a permission callback set to '__return_true', allowing unauthenticated access to course curriculum data without verifying the course's post status or user enrollment. This makes it possible for unauthenticated attackers to access detailed curriculum information for private, draft, scheduled, or password-protected courses by enumerating course IDs.

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-639: Authorization Bypass Through User-Controlled Key

Academy LMS <= 3.8.1 carries this weakness at __return_true, and reaching it takes no account at all. 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 Academy LMS the fix is 3.8.2: builds <= 3.8.1 are affected, anything from 3.8.2 onward is not.

Remediation

Update to version 3.8.2, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Academy LMS 3.8.2 closes this, and updating the plugin is the step that ends it.
