# OpenEMR: uploaded billing file lets a user run arbitrary SQL queries

Link for people: https://infrastack.ai/live/CVE-2026-126482 (this .md is for agents)

OpenEMR, an electronic health records system, builds a billing database query by pasting in a claim identifier from uploaded X12 835 remittance files without escaping it. An attacker who can log in with billing permissions, or who supplies a crafted payer file a clerk uploads, can read any table including password hashes and modify data.

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

## Affected

- vendor:OpenEMR affected range not listed fixed no fixed version listed

## How to check

- Check the OpenEMR version in the admin footer or `version.php`; versions before `8.5.0` are affected.
- Confirm whether billing users can upload ERA (X12 835) files through the billing module.

## Fix

- Upgrade OpenEMR to `8.5.0` or later.

## From the sources

OpenEMR before 8.5.0 contains an SQL injection vulnerability in SLEOB::slInvoiceNumber() in src/Billing/SLEOB.php, which concatenates the CLP01 claim identifier from uploaded X12 835 ERA files into a query without escaping or parameter binding. Authenticated users with billing permissions, or a malicious payer whose ERA file a clerk uploads, can execute arbitrary SQL to read any table, including users_secure password hashes, and modify data.
