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."}],"title":"KiviCare <= 4.4.0 - Missing Authorization to Unauthenticated Payment Bypass and Appointment Status Manipulation via /payment-success REST Endpoint","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/efe4223a-5c1a-401e-a46b-0278e96d2d71?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.4.0/app/controllers/api/AppointmentsController.php#L3931"},{"url":"https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.4.0/app/controllers/api/AppointmentsController.php#L465"},{"url":"https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.4.0/app/paymentGateways/KCPayLater.php#L109"},{"url":"https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.4.0/app/services/KCAppointmentPaymentService.php#L32"},{"url":"https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.4.0/app/baseClasses/KCPaymentGatewayFactory.php#L131"},{"url":"https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.3.0/app/controllers/api/AppointmentsController.php#L3931"},{"url":"https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.3.0/app/controllers/api/AppointmentsController.php#L465"},{"url":"https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.3.0/app/paymentGateways/KCPayLater.php#L109"},{"url":"https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.3.0/app/services/KCAppointmentPaymentService.php#L32"},{"url":"https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.3.0/app/baseClasses/KCPaymentGatewayFactory.php#L131"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3599918%40kivicare-clinic-management-system&new=3599918%40kivicare-clinic-management-system"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Niv Kochan"}],"timeline":[{"time":"2026-06-11T14:53:34.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-07-09T20:52:40.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-10T18:16:29.142482Z","id":"CVE-2026-11990","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-10T18:16:36.454Z"}}]}}
