## What is CVE-2026-11990?

CVE-2026-11990 is a medium-severity missing authorization vulnerability in iqonicdesign KiviCare – Clinic & Patient Management System (EHR), published on 10 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The KiviCare – Clinic & Patient Management System (EHR) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.4.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to mark arbitrary pending appointments as Confirmed and forge an associated completed payment record in wp_kc_payments_appointment_mappings using an attacker-supplied payment ID, bypassing payment entirely. This exploit is achievable on a default installation because the gateway resolution logic returns all registered gateways regardless of admin-enabled status, making the manual (KCPayLater) gateway always selectable.

Weakness: CWE-862 (Missing Authorization)
