      "value": "OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, an authorization bypass vulnerability in the patient portal signature endpoint allows authenticated portal users to upload and overwrite provider signatures by setting `type=admin-signature` and specifying any provider user ID. This could potentially lead to signature forgery on medical documents, legal compliance violations, and fraud. The issue occurs when portal users are allowed to modify provider signatures without proper authorization checks. Version 8.0.0 fixes the issue."

Antes de la versi\u00f3n 8.0.0, una vulnerabilidad de omisi\u00f3n de autorizaci\u00f3n en el endpoint de firma del portal del paciente permite a los usuarios autenticados del portal subir y sobrescribir firmas de proveedores estableciendo \u0027type=admin-signature\u0027 y especificando cualquier ID de usuario de proveedor. Esto podr\u00eda potencialmente conducir a la falsificaci\u00f3n de firmas en documentos m\u00e9dicos, violaciones de cumplimiento legal y fraude. El problema ocurre cuando a los usuarios del portal se les permite modificar firmas de proveedores sin las comprobaciones de autorizaci\u00f3n adecuadas. La versi\u00f3n 8.0.0 soluciona el problema."
