# OpenEMR: read-only users can transmit lab orders with patient data

Link for people: https://infrastack.ai/live/CVE-2026-126432 (this .md is for agents)

OpenEMR before 8.5.0 lets a logged-in user with read-only rights send lab orders to laboratories, because a permission check in the orders report page ignores write permission. The HL7 orders carry patient SSNs, insurance and diagnoses, and the attacker can mark them as transmitted.

_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: `8.5.0` or later is not affected by this entry.
- Review user accounts with read-only roles and confirm whether they can reach `interface/orders/list_reports.php`.

## Fix

- OpenEMR: upgrade to `8.5.0` or later.

## From the sources

OpenEMR before 8.5.0 contains an improper authorization vulnerability in interface/orders/list_reports.php that allows read-only users to transmit lab orders because the patients/med check ignores write permission. Authenticated attackers can submit form_xmit with arbitrary procedure order IDs to send HL7 orders containing SSNs, insurance, and diagnoses to laboratories and mark them transmitted.
