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 Profile Extra Fields by BestWebSoft plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the prflxtrflds_export_file function in versions up to, and including, 1.2.7. This makes it possible for unauthenticated attackers to expose potentially sensitive user data, including data entered into custom fields.

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.

The Profile Extra Fields WordPress plugin has a missing capability check on the prflxtrflds_export_file function, allowing unauthenticated attackers to export sensitive user profile data including custom fields without any authentication or authorization.

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

    In WordPress admin, go to Plugins > Installed Plugins and look for 'Bestwebsoft Profile Extra Fields' or check the plugin files in wp-content/plugins/profile-extra-fields/
    Affected if The plugin is installed and active
  2. Check the installed version

    Affected if Version is 1.2.7 or lower
  3. Locate the vulnerable function
    Access the plugin directory via FTP or file manager, then open the plugin's main PHP file and search for the function named 'prflxtrflds_export_file'
    Affected if The function exists in the codebase and is reachable via an AJAX hook or direct call
  4. Check for capability check on the export function
    Examine the prflxtrftrlds_export_file function and determine if it includes a WordPress capability check such as 'current_user_can' before processing or outputting data
    Affected if No capability check (like current_user_can) is present before data is processed or returned
