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. Check the Delucks SEO plugin version
    In WordPress admin, go to Plugins > Installed Plugins and find 'Delucks Seo' in the list. The version number is displayed below the plugin name. Alternatively, check the plugin main file header (usually in wp-content/plugins/delucks-seo/) for the 'Version' tag in the plugin comment block.
    Affected if The installed version is lower than 2.5.5 (e.g., 2.5.4, 2.5.0, 1.x.x, etc.)
  2. Verify the plugin is active
    Confirm the Delucks SEO plugin is enabled and running on the WordPress site. Check the Plugins page status column.
    Affected if The plugin is active and the version is below 2.5.5
  3. Identify if admin endpoints are accessible without authentication
    Test accessing common Delucks plugin admin URLs directly without logging in. Common paths include /wp-admin/admin.php?page=delucks-seo or similar SEO configuration pages. Attempt requests without providing admin credentials.
    Affected if Admin configuration pages load or return a successful response without requiring login credentials
  4. Check for unauthenticated API exposure
    If the plugin exposes REST API endpoints (e.g., /wp-json/delucks/v1/* or /wp-admin/admin-ajax.php?action=delucks*), attempt to call these endpoints without authentication.
    Affected if API endpoints respond successfully to unauthenticated requests and return SEO configuration data or allow settings changes

You are affected if the Delucks SEO plugin version is below 2.5.5 and sensitive SEO configuration functions or admin pages are accessible without proper authorization credentials.
