CVE-2026-13611Network attack vector

Unauthenticated data disclosure via unchecked REST endpoints

Published Sep 1, 2026 · Updated Sep 1, 2026

Missing authorization in KiviCare before 4.5.5 allows remote attackers to read patient rosters and configured payment gateway secret keys. Affected REST endpoint handlers return roster and gateway configuration data without checking authentication or authorization. No account is required; gateway-key exposure additionally requires a configured payment gateway, while roster exposure applies to affected installations.
