# OpenEMR: any logged-in user can change module admin settings

Link for people: https://infrastack.ai/live/CVE-2026-126457 (this .md is for agents)

OpenEMR before 8.5.0 has a missing authorization check in InstallerController, so any authenticated user can change module settings without the admin/manage_modules permission. Low-privileged staff such as front office clerks can reconfigure or partially disable installed modules.

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

## How to check

- Check the installed OpenEMR version and confirm whether it is below `8.5.0`
- Review which accounts can log in, since any authenticated user can reach these actions

## Fix

- OpenEMR: move to `8.5.0` or later

## From the sources

OpenEMR before 8.5.0 contains a missing authorization vulnerability in InstallerController that allows any authenticated user to modify module administration settings without the admin/manage_modules permission. Low-privileged users such as Front Office clerks can POST to saveConfig, DeleteAcl, DeleteHooks and nickName actions to reconfigure or partially disable installed modules.
