What is CVE-2026-13612?

The KiviCare WordPress plugin prior to version 4.5.2 fails to ensure that users can only access their own records, inadvertently allowing authenticated users to read sensitive information such as bills, invoices, and appointment details of other patients. This lack of adequate access verification poses a serious risk to patient confidentiality and data integrity.

Affected Version(s)

KiviCare 0 < 4.5.2
