📋 Description

OpenEMR before 8.4.0 contains an authorization bypass vulnerability that allows low-privileged authenticated users to read cross-patient FHIR QuestionnaireResponse data by sending the APICSRFTOKEN header. Attackers can reuse the session-exposed api_csrf_token_js value to skip FHIR scope checks and call GET /fhir/QuestionnaireResponse, exfiltrating site-wide questionnaire answer PHI.
