# OpenEMR: patient portal flaw lets patients change other patients' settings

Link for people: https://infrastack.ai/live/CVE-2026-124475 (this .md is for agents)

OpenEMR before 8.3.0 has an insecure direct object reference in portal/lib/persist.php, where a supplied setting_patient value is not checked against the logged-in patient. An authenticated patient portal user can insert or overwrite patient_settings rows for other patients, suppressing notifications, changing consent flags or altering portal preferences.

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

## How to check

- Check the installed OpenEMR version; versions before `8.3.0` are in the affected range.
- Look for `portal/lib/persist.php` in the OpenEMR install and whether the patient portal is enabled.

## Fix

- OpenEMR: move to `8.3.0` or later.

## From the sources

OpenEMR before 8.3.0 contains an insecure direct object reference vulnerability in portal/lib/persist.php that allows authenticated portal patients to modify other patients' settings by supplying an arbitrary setting_patient value. Attackers can insert or overwrite patient_settings rows for victims to suppress notifications, tamper with consent flags, or alter portal preferences.
