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
Missing Authorization vulnerability in RealMag777 MDTF wp-meta-data-filter-and-taxonomy-filter allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects MDTF: from n/a through <= 1.3.6.

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

Missing Authorization vulnerability in the MDTF (wp-meta-data-filter-and-taxonomy-filter) WordPress plugin allows unauthenticated or unauthorized users to access functionality that should be protected by access controls. The plugin fails to properly validate user permissions before executing certain actions, allowing exploitation of incorrectly configured security levels.

MitigationImplement proper authorization checks (capability verification and nonce validation) in the plugin code to ensure only users with appropriate permissions can access protected functionality, and update to a patched version when available.

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 MDTF plugin installation and version
    In WordPress admin, go to Plugins > Installed Plugins and locate 'MDTF - WP Meta Data Filter and Taxonomy Filter'. Note the version number displayed. Alternatively, check the plugin's main PHP file header or the version defined in the plugin's main file.
    Affected if The plugin is installed and the version is within the vulnerable range (compare your installed version to the affected ranges once they are published)
  2. Identify vulnerable AJAX endpoints
    Examine the plugin directory (wp-content/plugins/wp-meta-data-filter-and-taxonomy-filter/) for PHP files containing AJAX action hooks. Look for wp_ajax_ and wp_ajax_nopriv_ hooks that handle sensitive operations. Common patterns include wp_ajax_mdtf_* and wp_ajax_nopriv_mdtf_* actions.
    Affected if The plugin registers AJAX endpoints accessible via wp_ajax_nopriv_ hooks without capability checks (e.g., current_user_can() or admin references)
  3. Test AJAX endpoint authorization
    Send a direct POST request to wp-admin/admin-ajax.php with a known plugin action (such as mdtf_save_settings or similar) without providing authentication cookies or nonce tokens. Use a tool like curl: curl -X POST http://your-site.com/wp-admin/admin-ajax.php -d 'action=mdtf_your_action'
    Affected if The request executes successfully without returning an authorization error or requiring authentication
  4. Review capability verification in plugin code
    Open the plugin's main PHP files and search for function definitions handling user input or settings changes. Look for functions that should enforce permissions (like manage_options capability) but may lack current_user_can() checks before executing sensitive operations.
    Affected if Functions handling configuration or data modifications lack proper current_user_can() capability checks
  5. Check for nonce validation gaps
    In the plugin AJAX handlers, examine whether $_POST nonce fields are validated using wp_verify_nonce() or check_admin_referer() before processing requests, especially for actions accessible to unauthenticated users.
    Affected if AJAX handlers accept requests without validating nonce tokens or with weak nonce verification

A user is affected if the MDTF plugin is installed and certain actions/endpoints are accessible without authentication or proper capability checks, regardless of user role.
