# OpenEMR: missing access checks let tokens read any patient's documents

Link for people: https://infrastack.ai/live/CVE-2026-124449 (this .md is for agents)

OpenEMR before 8.4.0 has FHIR Media and QuestionnaireResponse read routes that skip access control checks. A non-patient API token without OpenEMR permissions can fetch any patient's documents and questionnaire responses by UUID.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the OpenEMR version in the installed application: `8.4.0` or later is not affected by this entry.
- Confirm whether the FHIR API is enabled and which API tokens exist for non-patient clients.

## Fix

- OpenEMR: upgrade to `8.4.0` or later.

## From the sources

OpenEMR before 8.4.0 contains a missing authorization vulnerability in FHIR Media/:uuid and QuestionnaireResponse read routes that skip ACL checks. Non-patient API tokens lacking OpenEMR ACLs can request resources by uuid, bypassing compartment filtering to read any patient's documents and questionnaire responses.
