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 Montonio for WooCommerce is installed
    Check for the plugin in WordPress admin under Plugins > Installed Plugins, or look for the /wp-content/plugins/montonio-for-woocommerce/ directory on the server
    Affected if The plugin is present in the WordPress installation
  2. Identify the installed plugin version
    In WordPress admin, click on the plugin to view details and see the version number, or open the main plugin file (e.g., montonio-for-woocommerce.php) and look for the 'Version' header comment
    Affected if The version shown is 10.1.2 or any version lower than 10.1.2
  3. Test for unauthenticated access to protected endpoints
    Send HTTP requests to common Montonio API endpoints (such as /wp-json/montonio/v1/* or any admin-ajax.php?action=montonio* actions) without providing any authentication tokens or cookies
    Affected if The endpoint returns valid data or performs actions without requiring login credentials
  4. Check WordPress authentication requirements on plugin AJAX actions
    Examine the plugin PHP code for AJAX handlers (wp_ajax_ and wp_ajax_nopriv_ hooks) and verify whether nopriv handlers expose sensitive functionality
    Affected if The plugin registers wp_ajax_nopriv_ actions that perform privileged operations

The environment is affected if Montonio for WooCommerce version 10.1.2 or lower is installed AND unauthenticated access to protected resources is possible without logging in.
