# OpenEMR: reflected cross-site scripting in search lets logged-in users run JavaScript

Link for people: https://infrastack.ai/live/CVE-2026-126475 (this .md is for agents)

OpenEMR before 8.5.0 reflects the searchEleNo POST parameter into an unencoded HTML attribute in auto-suggest.phtml, so a crafted payload runs JavaScript in the browser of a logged-in user. An attacker can use this to steal non-HttpOnly session cookies and view patient data.

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

## How to check

- Check the installed OpenEMR version in the application's version setting or `composer.json` and compare it with `8.5.0`.
- Look for the `searchEleNo` parameter handling in `application/index/search` and `auto-suggest.phtml` in the deployed code.

## Fix

- OpenEMR: upgrade to `8.5.0` or later.

## From the sources

OpenEMR before 8.5.0 contains a reflected cross-site scripting vulnerability that allows authenticated attackers to execute JavaScript by injecting payloads into the searchEleNo POST parameter of the application/index/search endpoint. Attackers can break out of unencoded HTML attributes in auto-suggest.phtml to inject event handlers that fire on DOM insertion, stealing non-HttpOnly session cookies and patient data.
