FKIE_CVE-2026-24898

Vulnerability from fkie_nvd - Published: 2026-03-03 22:16 - Updated: 2026-03-04 21:57
Summary
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0, an unauthenticated token disclosure vulnerability in the MedEx callback endpoint allows any unauthenticated visitor to obtain the practice's MedEx API tokens, leading to complete third-party service compromise, PHI exfiltration, unauthorized actions on the MedEx platform, and HIPAA violations. The vulnerability exists because the endpoint bypasses authentication ($ignoreAuth = true) and performs a MedEx login whenever $_POST['callback_key'] is provided, returning the full JSON response including sensitive API tokens. This vulnerability is fixed in 8.0.0.

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. La vulnerabilidad existe porque el endpoint omite la autenticaci\u00f3n ($ignoreAuth = true) y realiza un inicio de sesi\u00f3n de MedEx cada vez que se proporciona $_POST[\u0027callback_key\u0027], devolviendo la respuesta JSON completa, incluyendo tokens de la API sensibles. Esta vulnerabilidad se ha corregido en la versi\u00f3n 8.0.0."
