CVE-2026-124468 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 7.1 (high) and affects openemr; fixed in 8.3.0.

## Affected

- openemr: fixed in 8.3.0

## Description

OpenEMR before 8.3.0 contains an SQL injection vulnerability in the Standard REST API patient insurance and employer search, which concatenates query-string parameter names into SQL as column identifiers without escaping. Authenticated clients, including low-privilege patient-portal OAuth2 tokens, can send crafted parameter names to /api/patient/{puuid}/insurance or /api/patient/{puuid}/employer to extract patient PHI, user records, and API client secrets.

## What to do

## FAQ

### Is CVE-2026-124468 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What does this mean?

The Patient Insurance and Employer REST API does not properly handle input in its SQL queries. An authenticated user of the API can run arbitrary SQL against the OpenEMR database, reading patient PHI/PII, the users table, and API client secrets.
