Description from the CNA

The order cancellation function accepts an order identifier from the request and acts on that order without checking that the caller owns it. Any site visitor can set orders that are still awaiting payment to "canceled". This requires a page that contains the shop's order plugin. Orders that are already paid are not affected.
