Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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 summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Academy LMS WordPress plugin registers a '/topics' REST API endpoint with a permission callback set to '__return_true', which unconditionally allows any unauthenticated request. This endpoint returns course curriculum data without verifying the course's post status (private, draft, scheduled, password-protected) or checking user enrollment, enabling attackers to enumerate course IDs and access sensitive course materials.

MitigationReplace the '__return_true' permission callback with a custom function that verifies the course status is 'publish' AND confirms user enrollment before returning curriculum data, or update to a patched version if available from the vendor.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Academy LMS plugin installation
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Academy LMS', or check if the /wp-content/plugins/academy directory exists on the server
    Affected if Academy LMS plugin is present in the WordPress installation
  2. Determine Academy LMS version
    View the plugin version in the plugin admin panel, or read the version from the plugin header in file /wp-content/plugins/academy/academy.php
    Affected if The installed version matches any version of Academy LMS (the vulnerability exists in the plugin when the /topics endpoint is registered)
  3. Test unauthenticated access to the /topics REST API endpoint
    Send a GET request to https://yourdomain.com/wp-json/academy/v1/topics with a course_id parameter, for example: /wp-json/academy/v1/topics?course_id=1, using no authentication headers
    Affected if The request returns HTTP 200 with course curriculum data (lessons, topics, attachments) without requiring authentication
  4. Verify if private or draft course content is exposed
    Create a course set to 'Private', 'Draft', or 'Scheduled' status, then query the /topics endpoint using that course's ID without being logged in
    Affected if The endpoint returns curriculum data for non-published courses to unauthenticated users
  5. Confirm enrollment is not verified
    Query the /topics endpoint for a course the requesting user is not enrolled in, without being logged in
    Affected if The endpoint returns full curriculum content regardless of enrollment status

If the Academy LMS plugin is installed and the /topics REST API endpoint returns course curriculum data to unauthenticated requests, including private or non-enrolled course content, the environment is affected by this vulnerability.
