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 Ultimate Member Widgets for Elementor – WordPress User Directory plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the handle_filter_users function in all versions up to, and including, 2.3. This makes it possible for unauthenticated attackers to extract partial metadata of all WordPress users, including their first name, last name and email addresses.

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 Ultimate Member Widgets for Elementor plugin has a broken access control vulnerability in the handle_filter_users function. This function, used for filtering WordPress users in the Elementor widgets, lacks a capability check, allowing any unauthenticated request to query and retrieve sensitive user metadata including first names, last names, and email addresses.

MitigationUpdate the plugin to version 2.4 or later which includes the missing capability check, or implement a proper capability verification (current_user_can('list_users') or similar) on the handle_filter_users 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. Confirm plugin installation
    Check if the Ultimate Member Widgets for Elementor plugin is installed in your WordPress environment. Look in wp-content/plugins/ for a folder containing 'ultimate-member' and 'elementor' in the name, or check via WordPress admin under Plugins.
    Affected if The plugin is installed
  2. Check installed version
    Locate the main plugin file (usually ultimate-member-widgets-for-elementor.php or similar) and read the Version header in the plugin comments. Alternatively, check the version displayed in WordPress admin under Plugins.
    Affected if Version is less than 2.4
  3. Verify unauthenticated access to filter function
    Test if the AJAX endpoint used by handle_filter_users is reachable without authentication. This typically involves making a request to wp-admin/admin-ajax.php with action=um_elementor_filter_users (or similar) while logged out. Use a tool like curl: curl -X POST http://your-site.com/wp-admin/admin-ajax.php -d 'action=um_elementor_filter_users' -d 'filter_param=test'
    Affected if The request returns user data (first names, last names, email addresses) without requiring login
  4. Inspect function code for capability check
    If you have file access, locate the handle_filter_users function in the plugin source code. Check if it contains a current_user_can() call or similar capability verification at the beginning of the function.
    Affected if No capability check (such as current_user_can('list_users')) is present in the function

You are affected if the Ultimate Member Widgets for Elementor plugin is installed with a version earlier than 2.4 and its user filtering function is accessible to unauthenticated visitors.
