Description
OpenEMR before 8.3.0 contains an authorization bypass vulnerability in the patient portal onsitedocuments API that allows authenticated patients to read other patients' documents by overriding query criteria. Attackers can send empty pid_Equals and denialReason_IsNotLike parameters to remove patient scoping and locked filters, exposing consent bodies, signatures, file paths, and template data.
