CVE-2026-124481OpenEMR before 8.4.0 Cross-Patient Payment Tampering via Rainforest Portal Payments

Beschreibung

OpenEMR before 8.4.0 contains an improper authorization vulnerability in Rainforest patient portal payments that trusts browser-supplied patientId, encounter, and amount values instead of deriving them from the portal session. Authenticated portal patients can tamper with JSON sent to portal_payment.rainforest.php so the payin.authorized webhook writes forged ar_activity credits to other patients' encounters exceeding the amount actually paid.
