# OpenEMR: low-privilege users can alter other patients' tracker entries

Link for people: https://infrastack.ai/live/CVE-2026-126416 (this .md is for agents)

OpenEMR before 8.5.0 lets a low-privilege logged-in user change other patients' tracker entries by supplying arbitrary tracker_id values to patient_tracker_status.php. An attacker can alter patient-flow status, room assignments, and linked calendar appointment state.

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

## How to check

- Check the OpenEMR version in use; versions before `8.5.0` are listed as affected.
- Review whether patient_tracker_status.php is reachable by low-privilege accounts.

## Fix

- OpenEMR: move to `8.5.0` or later, per the NVD description.

## From the sources

OpenEMR before 8.5.0 contains an improper authorization vulnerability in patient_tracker_status.php that allows low-privilege authenticated users to modify other patients' tracker entries by supplying arbitrary tracker_id values. Attackers can post statustype and roomnum parameters with a valid CSRF token to alter patient-flow status, room assignments, and linked calendar appointment state.
