# OpenEMR: logged-in users can override global settings, disabling audit logging

Link for people: https://infrastack.ai/live/CVE-2026-126487 (this .md is for agents)

OpenEMR before 8.5.0 lets any authenticated user save keys with a global: prefix through the user settings endpoint, which overrides system-wide configuration. An attacker can turn off audit logging, weaken password policies, or change security settings that persist for their sessions.

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

## Affected

- vendor:OpenEMR affected range not listed fixed no fixed version listed

## How to check

- Check the installed OpenEMR version; anything below `8.5.0` is affected.
- Review the global configuration for audit logging and password policy settings after any user-level changes.

## Fix

- OpenEMR: upgrade to `8.5.0` or later.

## From the sources

OpenEMR before 8.5.0 contains an authorization bypass vulnerability that allows authenticated users to override system-wide global configuration values by storing global-prefixed keys through library/ajax/user_settings.php. Attackers can submit lab or target parameters with global: prefixed setting names to disable audit logging, weaken password policies, or alter security-sensitive settings persistently for their sessions.
