Shopware before 5.3.4 has a PHP Object Instantiation issue via the sort parameter to the loadPreviewAction() method of the Shopware_Controllers_Backend_ProductStream controller, with resultant XXE via instantiation of a SimpleXMLElement object.
The product uses an externally controlled name or reference that resolves to a resource that is outside of the intended control sphere.
