CVE-2023-3200
The MStore API plugin for WordPress is vulnerable to Cross-Site Request Forgery due to missing nonce validation on the mstore_update_new_order_message function.
Does this matter?
Lower severity and a low EPSS score (0.31%). Track it; it rarely justifies an emergency change on its own.
Description
The MStore API plugin for WordPress is vulnerable to Cross-Site Request Forgery due to missing nonce validation on the mstore_update_new_order_message function. This makes it possible for unauthenticated attackers to update new order message via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
