# OpenEMR: staff without prescription permission can read patient prescription data

Link for people: https://infrastack.ai/live/CVE-2026-126444 (this .md is for agents)

OpenEMR before 8.5.0 has a missing authorization check in its Ensora eRx integration. An authenticated staff user without the patients/rx permission can request eRx.php directly and read selected patients' demographic, medication and allergy data.

_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 (for example the version shown in the admin footer or `version.php`).
- Confirm whether the Ensora eRx integration is enabled in the installation.

## Fix

- Move OpenEMR to `8.5.0` or later.

## From the sources

OpenEMR before 8.5.0 contains a missing authorization vulnerability in the Ensora eRx integration that allows authenticated staff without patients/rx permission to access prescription data by directly requesting eRx.php. Attackers can expose selected patients' demographic, medication, and allergy data in the vendor XML and trigger eRx synchronization state changes.
