KiviCare public registration permits privileged doctor accounts
KiviCare before 4.5.2 lets an unauthenticated POST to /wp-json/kivicare/v1/auth/register select the doctor role. AuthController::checkRegistrationPermission() returns immediately when WordPress registration is enabled and otherwise treats missing role settings as allowed; register() repeats the fail-open check, maps the supplied user_role to KCDoctor, associates the supplied clinic and can default the account to active. An attacker who supplies the required registration data and a valid clinic ID can create privileged clinic staff with access to patient, billing and clinic data. Version 4.5.2 requires doctor and receptionist public registration to be explicitly enabled.

This CVE was published Aug 13, 2026 and is one of 22 known issues for this plugin.
Update, patch or deactivate.
Update to 4.5.2 or later immediately. Audit newly created KiviCare users and clinic assignments, remove unauthorized staff accounts, invalidate sessions, and assess accessed patient data under applicable privacy requirements.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
