# OpenEMR: low-privilege users can move and read other patients' documents

Link for people: https://infrastack.ai/live/CVE-2026-124486 (this .md is for agents)

OpenEMR before 8.3.0 lets a low-privilege logged-in user recategorize other patients' documents through the classic document controller. An attacker can then retrieve those documents to exfiltrate protected health information and alter charts.

_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 in the admin footer or `version.php` in the install directory.
- Confirm whether the instance is below `8.3.0`.

## Fix

- OpenEMR `8.3.0`

## Timeline

## From the sources

OpenEMR before 8.3.0 contains a missing authorization vulnerability in the classic document controller that allows low-privilege authenticated users to recategorize other patients' documents. Attackers can invoke move_action_process to move a document into a patients|demo category, then retrieve it with an empty patient_id to exfiltrate PHI and tamper with charts.
