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
Unauthenticated Broken Access Control in Motors <= 1.4.109 versions.

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

Unauthenticated Broken Access Control vulnerability in Motors theme/plugin version 1.4.109 and below allows attackers to access sensitive functionality or data without proper authentication. The CVSS 7.5 score indicates high exploitability with network-accessible attacks potentially exposing protected resources.

MitigationUpdate Motors to the latest version or implement proper authentication/authorization checks on all sensitive endpoints to enforce access controls.

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. Determine Motors theme/plugin version
    In WordPress admin, go to Appearance > Themes or Plugins > Installed Plugins. Locate the Motors theme or plugin and note the version number displayed.
    Affected if Version is 1.4.109 or lower
  2. Locate Motors installation directory
    Access your web server file system via FTP, SSH, or hosting file manager. Navigate to wp-content/themes/ (for theme) or wp-content/plugins/ (for plugin) and confirm the motors directory exists.
    Affected if Motors theme or plugin directory is present on the server
  3. Identify sensitive endpoints in Motors
    Examine the Motors plugin/theme files for PHP files containing functions that handle user data, listings, submissions, or administrative actions. Look for files in includes/ or classes/ directories that may expose protected functionality.
    Affected if Files handling sensitive data are found in the Motors installation
  4. Test unauthenticated access to sensitive functions
    Using a browser or HTTP tool (curl, Postman), attempt to access known Motors endpoints (such as AJAX handlers, API routes, or form submission handlers) without providing any authentication tokens or session cookies. Observe if the server responds with data or performs actions.
    Affected if Sensitive data is returned or privileged actions execute without authentication credentials

User is affected if Motors version is 1.4.109 or below AND any sensitive functionality or protected data is accessible without authentication.
