Antes de la versi\u00f3n 8.0.0, una vulnerabilidad de divulgaci\u00f3n de tokens no autenticada en el endpoint de callback de MedEx permite a cualquier visitante no autenticado obtener los tokens de la API de MedEx de la consulta, lo que lleva a un compromiso completo del servicio de terceros, exfiltraci\u00f3n de PHI, acciones no autorizadas en la plataforma MedEx y violaciones de HIPAA.
