# OpenEMR: missing access checks let low-privilege users change module settings

Link for people: https://infrastack.ai/live/CVE-2026-126479 (this .md is for agents)

OpenEMR before 8.5.0 has five Module Manager actions that skip the admin module-management permission check and CSRF validation. A low-privilege account such as Front Office can overwrite module configuration, redirect CCDA and HIE settings, and delete module hooks.

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

## How to check

- Find the installed OpenEMR version in the application's version file or admin footer and compare it with `8.5.0`.
- Check whether the Module Manager (InstallerController) is reachable by non-admin roles.

## Fix

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

## From the sources

OpenEMR before 8.5.0 contains a missing authorization vulnerability in five Module Manager InstallerController actions that lack the admin/manage_modules ACL check and CSRF validation. Low-privilege users such as Front Office accounts can POST to saveConfig or SaveHooks to overwrite any module's configuration, retarget CCDA and HIE settings, and delete module hooks.
