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 Moving Users plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.05 via the export functionality. The JSON files are stored in predictable locations with guessable file names when exporting user data. This could allow unauthenticated attackers to extract sensitive user data, for instance, email addresses, hashed passwords, and IP 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 · moderate confidence

The Moving Users WordPress plugin (versions up to 1.05) stores exported user data as JSON files in predictable, guessable locations accessible via direct URL. This allows unauthenticated attackers to enumerate and download these files, extracting sensitive data including email addresses, hashed passwords, and IP addresses.

MitigationDisable or remove the export functionality until a patched version is available, or implement .htaccess rules to block direct access to the export directory and add authentication checks to the export endpoint.

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 Moving Users plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Moving Users' or check the plugins directory (wp-content/plugins/moving-users) via file system
    Affected if The plugin is installed and active
  2. Check installed plugin version
    View the plugin's main PHP file header or check the WordPress plugin repository for the version number
    Affected if Version is 1.05 or lower (any version up to and including 1.05 is affected)
  3. Look for exported JSON files
    Search the wp-content/uploads directory and any plugin-specific export directories for .json files containing user data (look for files with fields like email, password, IP addresses)
    Affected if Any JSON files containing user export data exist on the server
  4. Test web accessibility of export directory
    Attempt to access common export paths (such as wp-content/uploads/moving-users/ or similar predictable locations) via HTTP request to see if files are directly downloadable
    Affected if The export directory or JSON files are accessible via direct URL without authentication
  5. Review web server access logs
    Search access logs for requests to .json files in plugin-related paths, especially from unauthenticated or external IP addresses
    Affected if Logs show unauthorized access to JSON export files

A user is affected if the Moving Users plugin versions 1.05 or below is installed and JSON export files exist and are accessible via web without authentication.
