# OpenEMR: missing authorization and SQL injection let clerks read the database

Link for people: https://infrastack.ai/live/CVE-2026-126455 (this .md is for agents)

OpenEMR before 8.5.0 has several missing authorization checks and SQL injection flaws in its report, patient portal, transaction and immunization components. A low-privileged Front Office clerk can chain them to read arbitrary database tables, including password hashes, take over patient portal accounts and forge approved clinical records.

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

## How to check

- Check the OpenEMR version in the installation; the sources say versions before `8.5.0` are affected.
- Confirm whether the patient portal and report features are in use on the instance.

## Fix

- Upgrade OpenEMR to `8.5.0` or later.

## From the sources

OpenEMR before 8.5.0 contains multiple missing authorization and SQL injection defects across report, portal, transaction, and immunization components. Low-privileged Front Office clerks can chain these to read arbitrary database tables including users_secure hashes, hijack patient portal identities, and forge approved clinical records.
