{"id":"CVE-2026-11990","state":"PUBLISHED","title":"KiviCare <= 4.4.0 - Missing Authorization to Unauthenticated Payment Bypass and Appointment Status Manipulation via /payment-success REST Endpoint","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.","publishedAt":"2026-07-10T09:32:45.502Z","updatedAt":"2026-07-10T18:16:36.454Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["iqonicdesign KiviCare – Clinic & Patient Management System (EHR)"],"affected":[{"vendor":"iqonicdesign","product":"KiviCare – Clinic & Patient Management System (EHR)","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.4.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/efe4223a-5c1a-401e-a46b-0278e96d2d71?source=cve","https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.4.0/app/controllers/api/AppointmentsController.php#L3931","https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.4.0/app/controllers/api/AppointmentsController.php#L465","https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.4.0/app/paymentGateways/KCPayLater.php#L109","https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.4.0/app/services/KCAppointmentPaymentService.php#L32","https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.4.0/app/baseClasses/KCPaymentGatewayFactory.php#L131","https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.3.0/app/controllers/api/AppointmentsController.php#L3931","https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.3.0/app/controllers/api/AppointmentsController.php#L465","https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.3.0/app/paymentGateways/KCPayLater.php#L109","https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.3.0/app/services/KCAppointmentPaymentService.php#L32","https://plugins.trac.wordpress.org/browser/kivicare-clinic-management-system/tags/4.3.0/app/baseClasses/KCPaymentGatewayFactory.php#L131","https://plugins.trac.wordpress.org/changeset?reponame=&old=3599918%40kivicare-clinic-management-system&new=3599918%40kivicare-clinic-management-system"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/11xxx/CVE-2026-11990.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-11990","state":"PUBLISHED","datePublished":"2026-07-10T09:32:45.502Z","dateUpdated":"2026-07-10T18:16:36.454Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-11T14:38:19.971Z"},"containers":{"cna":{"title":"KiviCare <= 4.4.0 - Missing Authorization to Unauthenticated Payment Bypass and Appointment Status Manipulation via /payment-success REST Endpoint","descriptions":[{"lang":"en","value":"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.
