# OpenEMR: read-only drug users can record fake medication dispenses

Link for people: https://infrastack.ai/live/CVE-2026-126433 (this .md is for agents)

OpenEMR before 8.5.0 checks only drug view permission in its dispense page, so users with read-only drug access can record fake dispensing events. An attacker can create false dispensing records and reduce drug inventory counts.

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

## How to check

- Check the OpenEMR version in the installed application: `unknown` command not given by sources
- Confirm whether users with read-only drug administration access exist in the admin permission settings

## Fix

- OpenEMR: `8.5.0` or later

## Timeline

## Documents

- [advisory] Vendor advisory: github.com https://github.com/openemr/openemr/security/advisories/GHSA-hp8p-h8g8-xmg3
- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/openemr-before-8.5.0-improper-authorization-via-dispense-drug-php

## From the sources

OpenEMR before 8.5.0 contains an improper authorization vulnerability in interface/drugs/dispense_drug.php, which checks only for admin/drugs view permission instead of write permission before dispensing medication. Authenticated users with read-only drug administration access can send GET requests with drug_id, quantity, fee, and encounter parameters to create false dispensing records and decrement inventory.
