The REST API TO MiniProgram plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.1.2. This is due to the permission callback (update_user_wechatshop_info_permissions_check) only validating that the supplied openid parameter corresponds to an existing WordPress user, while the callback function (update_user_wechatshop_info) uses a separate, attacker-controlled userid parameter to determine which users metadata gets modified, with no verification that the openid and userid belong to the same user. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify arbitrary users store-related metadata (storeinfo, storeappid, storename) via the userid REST API parameter.
