# OpenEMR: patient portal SQL injection exposes whole database to patients

Link for people: https://infrastack.ai/live/CVE-2026-126488 (this .md is for agents)

OpenEMR before 8.5.0 has an SQL injection flaw in the patient portal OnsiteDocument.Query endpoint, where the _BitwiseAnd parameters go into SQL unquoted. An authenticated patient can read the whole database, including other patients' records and staff password hashes.

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

## How to check

- Check the installed OpenEMR version against the fixed release, `8.5.0`
- Confirm whether the patient portal is enabled on the deployment

## Fix

- OpenEMR: upgrade to `8.5.0` or later

## Timeline

## From the sources

OpenEMR before 8.5.0 contains an SQL injection vulnerability in the patient portal OnsiteDocument.Query endpoint, where mass-assigned _BitwiseAnd criteria parameters are placed unquoted into SQL with only quote-character escaping. Authenticated portal patients can inject SQL outside their per-patient scope to read the entire database, including other patients' demographics and users_secure password hashes.
