The ReviewX – Multi-criteria Rating & Reviews for WooCommerce plugin for WordPress is vulnerable to unauthorized deletion of data due to a missing capability check on the reviewx_remove_guest_image function in all versions up to, and including, 1.6.27. This makes it possible for authenticated attackers, with subscriber access and above, to delete attachments.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
