# OpenEMR: low-privilege users can read restricted patient data and suppress lab orders

Link for people: https://infrastack.ai/live/CVE-2026-126435 (this .md is for agents)

OpenEMR before 8.5.0 lets a user with only medication-view permission request any order ID through interface/orders/order_manifest.php and read patient data outside their squad restrictions. The same page accepts a state change without a CSRF token that sets do_not_send flags, suppressing ordered lab procedures.

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

## How to check

- Check the OpenEMR version in use; the sources state versions before `8.5.0` are affected.
- Look at whether `interface/orders/order_manifest.php` is present and reachable on the deployment.

## Fix

- OpenEMR: move to `8.5.0` or later (the sources state the fix is in versions from `8.5.0`).

## From the sources

OpenEMR before 8.5.0 contains an improper authorization vulnerability in interface/orders/order_manifest.php, which checks patients/med without requiring write access or applying patient squad restrictions. Users with only patients/med view permission can request any order ID to read squad-restricted patient data and submit bn_save and form_omit parameters, without a CSRF token, to set do_not_send flags that suppress ordered lab procedures.
