Estado: ModificadaAlta (7.5)—

La implementación del protocolo OpenRTB 2.3 en Interactive Advertising Bureau (IAB) podría permitir que atacantes remotos enmascaren el estado de las transacciones ad y comprometan la integridad de bid aprovechando el error a la hora de limitar el tiempo entre las respuestas bid y las notificaciones "impression". Esto también se conoce como "Amnesia Bug".
