# OpenEMR: REST API insurance search lets authenticated users run SQL

Link for people: https://infrastack.ai/live/CVE-2026-124468 (this .md is for agents)

OpenEMR's Standard REST API builds SQL from query-string parameter names in its patient insurance and employer search without escaping them. An authenticated client, including a low-privilege patient-portal token, can read patient health records, user records and API client secrets.

_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 `8.3.0` are affected
- Look for patient-portal OAuth2 clients and API access enabled on the Standard REST API

## Fix

- OpenEMR: upgrade to `8.3.0` or later

## From the sources

OpenEMR before 8.3.0 contains an SQL injection vulnerability in the Standard REST API patient insurance and employer search, which concatenates query-string parameter names into SQL as column identifiers without escaping. Authenticated clients, including low-privilege patient-portal OAuth2 tokens, can send crafted parameter names to /api/patient/{puuid}/insurance or /api/patient/{puuid}/employer to extract patient PHI, user records, and API client secrets.
