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 · moderate confidence

Cross-Site Request Forgery (CSRF) vulnerability in the MasterStudy LMS WordPress plugin allows remote attackers to induce authenticated users to perform unintended actions by tricking them into submitting malicious requests. The plugin fails to properly validate anti-CSRF tokens (nonces) on state-changing operations such as form submissions and AJAX requests.

MitigationImplement WordPress nonces (wp_nonce_field) on all forms and AJAX actions, verify nonce validation in request handlers, and validate Origin/Referer headers to ensure requests originate from trusted sources.

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. Identify MasterStudy LMS installation
    In WordPress admin, go to Plugins > Installed Plugins and locate 'MasterStudy LMS - Online Learning, Course Management LMS'. Note the version number displayed. Alternatively, check the plugin main PHP file (typically /wp-content/plugins/masterstudy-lms/) for the version defined in the plugin header comment.
    Affected if Plugin is installed with version lower than 3.2.2 (e.g., 3.2.1, 3.2.0, earlier versions)
  2. Locate state-changing forms
    Inspect plugin PHP files that handle form submissions. Look for files containing form handlers, particularly in /classes/ or /controllers/ directories. Search for $_POST or $_GET handling that processes user input without subsequent nonce verification.
    Affected if Forms exist that process state-changing requests (user registrations, course enrollments, profile updates) without calling wp_verify_nonce() or check_ajax_referer()
  3. Verify nonce field presence in forms
    Examine frontend form templates (.phtml or .php files in /views/ or /templates/ directories). Search for calls to wp_nonce_field() or wp_create_nonce() before form closing tags. Check AJAX JavaScript files for nonce inclusion in request data.
    Affected if Forms or AJAX handlers that submit state-changing data lack nonce fields (wp_nonce_field) in their markup or nonce parameter in their request payloads
  4. Inspect AJAX action handlers
    Review files registering AJAX endpoints (add_action('wp_ajax_...')). Verify that each handler calls check_ajax_referer() or wp_verify_nonce() early in the function before processing the request.
    Affected if AJAX action handlers process requests without verifying nonce validity, allowing forged requests from other sites

You are affected if the MasterStudy LMS plugin version is below 3.2.2 AND your site processes state-changing requests (form submissions or AJAX calls) through this plugin without proper nonce validation.

Upgrade available Upgrade to 3.2.2 or later
Fixed in 3.2.2
Interim mitigation

Implement WordPress nonces (wp_nonce_field) on all forms and AJAX actions, verify nonce validation in request handlers, and validate Origin/Referer headers to ensure requests originate from trusted sources.

Recommended fix High confidence

MasterStudy LMS version 3.2.2

  1. Log in to the WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Find MasterStudy LMS in the plugin list
