Advisory
Source description from Wordfence Intelligence.
The MultiVendorX plugin for WordPress is vulnerable to unauthorized access of data, modification of data, and loss of data due to an improper capability check on the 'save_settings_permission' function for the REST routes instantiated by the 'mvx_rest_routes_react_module' function versions up to, and including, 4.0.25. This makes it possible for unauthenticated attackers to create, update, and delete vendors, retrieve sensitive information, and modify plugin settings.
