CVE-2026-2991
HighSummary
Wtyczka KiviCare – System Zarządzania Kliniką i Pacjentami (EHR) dla WordPressa jest podatna na obejście uwierzytelniania we wszystkich wersjach do 4.1.2 włącznie. Funkcja `patientSocialLogin()` nie weryfikuje tokenu dostępu dostawcy społecznościowego przed uwierzytelnieniem użytkownika, co pozwala nieautoryzowanym atakującym na logowanie się jako dowolny pacjent zarejestrowany w systemie.
Risk Assessment
Atakujący może uzyskać dostęp do wrażliwych danych medycznych, wizyt, recept oraz informacji o płatnościach, co prowadzi do naruszenia danych osobowych i zdrowotnych (PII/PHI). Dodatkowo, ciasteczka uwierzytelniające są ustawiane przed sprawdzeniem ról, co stwarza ryzyko dla użytkowników niebędących pacjentami, w tym administratorów.
Recommendation
Zaleca się aktualizację wtyczki KiviCare do najnowszej wersji, aby usunąć tę podatność. Należy również przeprowadzić audyt dostępu do danych wrażliwych oraz monitorować logi systemowe w celu wykrycia potencjalnych naruszeń.

Original NVD description (English source)
The KiviCare – Clinic & Patient Management System (EHR) plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 4.1.2. This is due to the `patientSocialLogin()` function not verifying the social provider access token before authenticating a user. This makes it possible for unauthenticated attackers to log in as any patient registered on the system by providing only their email address and an arbitrary value for the access token, bypassing all credential verification. The attacker gains access to sensitive medical records, appointments, prescriptions, and billing information (PII/PHI breach). Additionally, authentication cookies are set before the role check, meaning the auth cookies for non-patient users (including administrators) are also set in the HTTP response headers, even though a 403 response is returned.
