OpenEMR before 8.4.0 contains an authorization bypass vulnerability that allows patient-scoped SMART tokens to read other patients' questionnaire responses because FhirQuestionnaireResponseService does not implement IPatientCompartmentResourceService. Attackers holding a patient/QuestionnaireResponse.rs token can request responses by uuid or list the unfiltered bundle to obtain cross-patient clinical assessment answers.
