# OpenEMR: crafted EDI upload lets billing users run SQL and extract patient data

Link for people: https://infrastack.ai/live/CVE-2026-126460 (this .md is for agents)

OpenEMR before 8.5.0 concatenates the CLP01 claim control number from uploaded X12 835 ERA files into a SQL query without escaping. A user with billing write access can upload a crafted file that is stored and triggers a time-based SQL injection when reprocessed, extracting patient health information.

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

## How to check

- Check the installed OpenEMR version in the admin footer or `version.php` and compare against `8.5.0`
- Review who holds billing write access, since they can upload ERA files

## Fix

- OpenEMR: move to `8.5.0` or later

## From the sources

OpenEMR before 8.5.0 contains a persistent SQL injection vulnerability in SLEOB::slInvoiceNumber(), where the CLP01 claim control number from uploaded X12 835 ERA files is concatenated unescaped into a query. Attackers with billing write access can upload a crafted .edi file via sl_eob_search.php that is stored on the server and re-executes a time-based payload whenever it is reprocessed through sl_eob_process.php, extracting patient health information.
