# OpenEMR: authenticated users can read other patients' prescriptions via print page

Link for people: https://infrastack.ai/live/CVE-2026-126441 (this .md is for agents)

OpenEMR before 8.5.0 has an insecure direct object reference in the CAMOS rx_print.php printer, so a logged-in user can submit forged chrx_ prescription IDs. An attacker can read other patients' drug names, dosages, directions and refill counts without medication permissions.

_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; versions below `8.5.0` are affected.
- Confirm whether the CAMOS module is in use and whether `rx_print.php` is reachable.

## Fix

- OpenEMR: move to `8.5.0` or later.

## From the sources

OpenEMR before 8.5.0 contains an insecure direct object reference vulnerability in the CAMOS rx_print.php printer that allows authenticated users to read other patients' prescriptions. Attackers can submit forged chrx_ parameters with global prescription IDs to disclose drug names, dosages, directions, and refill counts without medication permissions.
