KiviCare WordPress Plugin Authorization Flaws

The KiviCare clinic management plugin for WordPress contains a critical privilege escalation vulnerability allowing unauthenticated attackers to create new clinics and administrative users through an unprotected REST API endpoint. All versions up to and including 4.1.2 are affected. With a CVSS score of 8.2 and network-based exploitation requiring no authentication, this represents a significant risk to healthcare data confidentiality and system integrity, though no active exploitation (KEV) or public proof-of-concept has been documented at this time.

The KiviCare Clinic & Patient Management System (EHR) plugin for WordPress contains a critical authentication bypass vulnerability allowing unauthenticated attackers to log in as any patient by simply providing their email address and an arbitrary access token value. All versions up to and including 4.1.2 are affected, exposing sensitive medical records, appointments, prescriptions, and billing information (PII/PHI). The CVSS score of 9.8 reflects the severity of unauthenticated remote exploitation with high impact to confidentiality, integrity, and availability.
