# OpenEMR: low-privilege users can pull any patient's full clinical record

Link for people: https://infrastack.ai/live/CVE-2026-124487 (this .md is for agents)

OpenEMR before 8.4.0 lets a user with only demographics and documents permissions generate a CCDA for any patient through the non-patient /fhir/DocumentReference/$docref route. The attacker can then download the full-chart CCDA and extract clinical data.

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

## How to check

- Check the installed OpenEMR version against the fixed release in the product ranges.

## Fix

- OpenEMR: move to `8.4.0` or later.

## From the sources

OpenEMR before 8.4.0 contains an improper authorization vulnerability in the non-patient POST /fhir/DocumentReference/$docref route that allows low-privileged users to generate any patient's CCDA. Attackers with only demographics and documents permissions can supply a victim patient parameter, then download the full-chart CCDA from Patient Documents to exfiltrate clinical data.
