# CVE-2026-124468: OpenEMR before 8.3.0 SQL Injection via Patient Insurance and Employer REST API

Status: published. Published: 2026-11-08. Updated: 2026-11-12.

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.
