# OpenEMR: SQL injection in Syndromic Surveillance report exposes patient records

Link for people: https://infrastack.ai/live/CVE-2026-126478 (this .md is for agents)

OpenEMR before 8.5.0 concatenates the form_icd_codes[] POST array into an unquoted numeric IN() clause without integer validation in the Syndromic Surveillance report. An authenticated user can send quote-free payloads to run blind or UNION-based SQL injection and extract 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 application footer or `version.php` and compare it with the fixed range.
- Confirm whether the Syndromic Surveillance report is in use on the deployment.

## Fix

- OpenEMR: move to `8.5.0` or later (the fixed version named in the NVD range for this CVE).

## From the sources

OpenEMR before 8.5.0 contains an SQL injection vulnerability in the Syndromic Surveillance report because the form_icd_codes[] POST array is concatenated into an unquoted numeric IN() clause without integer validation. Authenticated users can submit quote-free payloads that bypass add_escape_custom to perform blind or UNION-based injection and exfiltrate patient health information.
