# OpenEMR: SQL injection in patient portal lets staff read PHI and hashes

Link for people: https://infrastack.ai/live/CVE-2026-126465 (this .md is for agents)

OpenEMR, an electronic health records system, has an SQL injection flaw in its patient portal api/onsiteactivityviews endpoint, fixed in version 8.5.0. Any authenticated staff user can inject SQL and read patient health data, staff password hashes, MySQL credentials and API tokens.

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

## How to check

- Check the installed OpenEMR version; versions before `8.5.0` are affected.
- Confirm whether the patient portal and the `api/onsiteactivityviews` endpoint are enabled on the deployment.

## Fix

- Upgrade OpenEMR to `8.5.0` or later.

- [advisory] Vendor advisory: github.com https://github.com/openemr/openemr/security/advisories/GHSA-vvj8-xpx8-p293

## From the sources

OpenEMR before 8.5.0 contains an SQL injection vulnerability in the patient portal api/onsiteactivityviews endpoint that allows any authenticated staff user to inject SQL through unquoted Id_BitwiseAnd Criteria values. Attackers can close the bitwise parenthesis and append OR or UNION SELECT clauses to read patient PHI, staff password hashes, MySQL authentication strings, and API tokens.
