CVE-2026-124445: OpenEMR OneTimeAuth token replay and PIN brute force

CVE-2026-124445 · Severity: critical · CVSS 9.8 · Published 2026-11-08

OpenEMR is a medical records and practice management system used by healthcare providers to store and manage patient information including sensitive health data (PHI). A flaw in the authentication token system allows attackers who obtain a patient portal login token to replay it indefinitely or guess a 6-digit PIN without rate limiting, gaining unauthorized access to patient records including medical history, prescriptions, and personal information.

Technical details

The OneTimeAuth component in src/Common/Auth/OneTimeAuth.php fails to enforce the enforce_onetime_use and max_access_count security flags during token consumption, allowing unlimited replay of captured service_auth tokens for their full lifetime (up to 14 days). Additionally, the PIN validation lacks rate limiting, account lockout, or cryptographic comparison (uses loose != instead of ===), enabling brute-force attacks on the 151,200-permutation PIN space and bypass via type juggling with numeric equivalents.
