      "value": "OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.1, a stored cross-site scripting vulnerability in the prescription CSS/HTML multi-print feature allows a patient portal user to execute arbitrary JavaScript in a clinician\u0027s browser session. Patient demographic fields (name, address) are rendered without output encoding in multiprintcss_header(), and portal patients can write attacker-controlled HTML directly into patient_data by calling the PUT api/patient/:num endpoint, which bypasses the intended audit review workflow. Because the XSS fires in the clinician\u0027s authenticated session on the main OpenEMR interface, the attacker can access CSRF tokens, session data, and perform actions as the clinician \u2014 crossing the patient-to-clinician trust boundary. This issue has been patched in version 8.0.0.1."

Antes de la versi\u00f3n 8.0.0.1, una vulnerabilidad de cross-site scripting almacenado en la funci\u00f3n de impresi\u00f3n m\u00faltiple CSS/HTML de prescripciones permite a un usuario del portal de pacientes ejecutar JavaScript arbitrario en la sesi\u00f3n del navegador de un m\u00e9dico. Los campos demogr\u00e1ficos del paciente (nombre, direcci\u00f3n) se renderizan sin codificaci\u00f3n de salida en multiprintcss_header(), y los pacientes del portal pueden escribir HTML controlado por el atacante directamente en patient_data llamando al endpoint PUT api/patient/:num, lo que omite el flujo de trabajo de revisi\u00f3n de auditor\u00eda previsto. Debido a que el XSS se activa en la sesi\u00f3n autenticada del m\u00e9dico en la interfaz principal de OpenEMR, el atacante puede acceder a tokens CSRF, datos de sesi\u00f3n y realizar acciones como el m\u00e9dico - cruzando el l\u00edmite de confianza entre paciente y m\u00e9dico. Este problema ha sido parcheado en la versi\u00f3n 8.0.0.1."
