CVE-2026-25146Public exploitNetwork attack vector

Payment API key disclosure via client-side rendering

Published Mar 3, 2026 · Updated Mar 3, 2026

Sensitive-data exposure in OpenEMR 5.0.2 and later before 8.0.0 allows remote authenticated users to obtain payment gateway API keys. The front_payment.php and portal_payment.php paths decrypt gateway_api_key and emit it into a client-side apiKey variable for every configured gateway. Payments must be enabled and a key configured; a patient-portal or staff user who reaches a payment page can read the plaintext key and use it for provider-dependent fraud or account takeover.
