The MStore API plugin for WordPress is vulnerable to Cross-Site Request Forgery due to missing nonce validation on the mstore_update_status_order_message function. This makes it possible for unauthenticated attackers to update status order message via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
