# OpenEMR: stored SQL injection through C-CDA field identifiers leaks patient records

Link for people: https://infrastack.ai/live/CVE-2026-126431 (this .md is for agents)

OpenEMR before 8.5.0 lets an authenticated Carecoordination user store malicious C-CDA field identifiers through the savedata action. When C-CDA generation later builds an IN clause from them, the stored input runs as SQL, so an attacker can extract password hashes, portal reset values and patient records.

_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; affected versions are those before `8.5.0`.

## Fix

- OpenEMR: move to `8.5.0` or later (the sources state the fix is in versions before `8.5.0` being affected).

## From the sources

OpenEMR before 8.5.0 contains a second-order sql injection vulnerability that allows authenticated Carecoordination users to store malicious C-CDA field identifiers through the savedata action. Attackers can inject SQL into the IN clause built by fetchFormValues() during C-CDA generation to extract password hashes, portal reset values, and patient records.
