The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to sensitive information disclosure of a WordPress site's database due to missing capability checks on the wp_ajax_wpvivid_add_remote AJAX action that allows low-level authenticated attackers to send back-ups to a remote location of their choice for review. This affects versions up to, and including 0.9.35.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
