The Dokan: AI Powered WooCommerce Multivendor Marketplace Solution plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.3.1 via the '/dokan/v1/stores/{id}/reviews' REST API endpoint. This is due to the 'prepare_reviews_for_response' method including reviewer email addresses, usernames, and user IDs in the API response. This makes it possible for unauthenticated attackers to extract email addresses, usernames, and user IDs of all customers who left reviews on any vendor's store. The Pro version of the plugin must be installed and activated, with store reviews enabled, in order to exploit the vulnerability.
