CVE-2026-124476
Published:November 08, 2026
Updated:November 09, 2026
OpenEMR before 8.3.0 contains an insecure direct object reference in portal/lib/paylib.php, which writes the request-supplied form_pid (or the patient_id_cc value in Sphere data) to onsite_portal_activity without checking it against the session patient. Authenticated portal patients can submit portal-save, review-save, AuthorizeNet, Stripe, or Sphere requests to insert or modify forged payment-audit records in other patients' billing records.
