# OpenEMR: authenticated users can send clinic Direct messages without permission

Link for people: https://infrastack.ai/live/CVE-2026-126447 (this .md is for agents)

OpenEMR before 8.5.0 has a missing authorization check in trusted-messages-ajax.php. Any logged-in core user, even one with no ACL permissions, can send Direct messages through the clinic's phiMail credentials to chosen recipients with chosen content.

_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 user accounts with no ACL permissions to see whether they can reach trusted-messages-ajax.php.

## Fix

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

## From the sources

OpenEMR before 8.5.0 contains a missing authorization vulnerability in trusted-messages-ajax.php that allows any authenticated core user to send Direct messages without the patients/notes permission. Attackers with zero-ACL accounts can submit chosen recipients and message bodies sent via the clinic's phiMail credentials, impersonating the clinic to deliver fraudulent clinical communications.
