This plugin is prone to a reflected cross site scripting vulnerability, because these parameters are not sanitized: "Address Region", "Longitude", "Latitude", "Event type", "Offer aggregate", "Low Price", "High Price", "Offer Url", "Price", "Events Website", "Offer Quantity", "Price valid Until", "Tickets currency", "Start Date", "End Date", "Street Address", "Address Locality", "Event Name", "Events Url", "Photo" and "Location".
