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 LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the catch_lp_ajax function in all versions up to, and including, 4.3.2. This makes it possible for unauthenticated attackers to modify course contents by adding/removing/updating/re-ordering sections or modifying section items.

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 LearnPress WordPress LMS plugin fails to enforce authorization checks on its catch_lp_ajax function, allowing unauthenticated users to make AJAX calls that modify course data. Attackers can add, remove, update, or reorder course sections and items without any authentication or capability verification.

MitigationUpdate LearnPress to version 4.3.2 or later, and implement proper capability checks (current_user_can()) and nonce validation on all AJAX endpoints in the catch_lp_ajax function.

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. Verify LearnPress plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and confirm LearnPress is listed and active
    Affected if LearnPress plugin is present and active in WordPress
  2. Determine installed LearnPress version
    Check the plugin file header in wp-content/plugins/learnpress/learnpress.php or view the plugin version displayed in the Plugins admin page
    Affected if Version is lower than 4.3.2 (vulnerable versions are any release before 4.3.2)
  3. Inspect the catch_lp_ajax function for authorization gaps
    Access the plugin source file containing catch_lp_ajax function and verify if current_user_can() or similar capability checks are performed before processing AJAX requests
    Affected if No capability verification (current_user_can) is found in the catch_lp_ajax function or its called methods
  4. Test AJAX endpoint accessibility without authentication
    Send a crafted POST request to your site's wp-admin/admin-ajax.php with a LearnPress AJAX action (such as lp_update_course_section order) without including any authentication cookies or nonces
    Affected if The AJAX call executes successfully and modifies course data without returning an authentication or capability error

You are affected if LearnPress is installed with a version earlier than 4.3.2 and the catch_lp_ajax function processes requests without verifying user authentication or capabilities.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update LearnPress to version 4.3.2 or later, and implement proper capability checks (current_user_can()) and nonce validation on all AJAX endpoints in the catch_lp_ajax function.

Recommended fix Moderate confidence

Latest version of LearnPress (beyond 4.3.2)

  1. Log in to WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Find 'LearnPress – WordPress LMS Plugin'
  4. Click 'Update Now' if an update is available, or manually download the latest version from wordpress.org/plugins/learnpress and upload it
