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 Sensitive Data Exposure in Kit (formerly ConvertKit) for WooCommerce <= 2.1.5 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

The Kit (formerly ConvertKit) plugin for WooCommerce versions 2.1.5 and below allows unauthenticated attackers to access sensitive data due to missing or inadequate authorization controls on certain endpoints. This exposure occurs without requiring any authentication credentials.

MitigationUpdate the Kit for WooCommerce plugin to a version newer than 2.1.5, or implement proper authentication/authorization checks on all sensitive endpoints to prevent unauthenticated access to sensitive data.

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 Kit for WooCommerce plugin is installed
    Check the WordPress plugin directory for the Kit (formerly ConvertKit) plugin, or look in wp-content/plugins/ for a folder containing 'kit' or 'convertkit' in the name
    Affected if The plugin folder exists in the WordPress installation
  2. Determine the installed plugin version
    Check the main plugin file header (usually plugin-name.php in the plugin folder) for the 'Version:' comment, or view the plugin in WordPress admin under Plugins > Installed Plugins
    Affected if The reported version is 2.1.5 or lower
  3. Check if the site is running WooCommerce
    Look for the WooCommerce plugin in wp-content/plugins/woocommerce/ or check WooCommerce status in WordPress admin under WooCommerce > Status
    Affected if WooCommerce is active and the Kit plugin is installed
  4. Test for unauthenticated endpoint access
    Send HTTP requests to common Kit API endpoints without providing any authentication headers or credentials to see if they return sensitive data
    Affected if Requests to Kit plugin endpoints succeed without authentication and return sensitive information

The environment is affected if the Kit for WooCommerce plugin versions 2.1.5 or below is installed alongside WooCommerce and its sensitive endpoints are accessible without authentication.
