The Reviso Exporter for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and missing nonce verification on the disconnect_callback() function in versions up to, and including, 1.2.3. The function is registered to the 'wp_ajax_wcefr-disconnect' AJAX action and unconditionally calls delete_option('wcefr-agt'), which removes the Reviso Agreement Grant Token used to authenticate API calls. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete the plugin's stored Agreement Grant Token, breaking the connection between WooCommerce and the Reviso service.
