KiviCare <= 4.5.0 - Authenticated (Doctor+) SQL Injection via 'orderby' Parameter in DoctorSessionController
The KiviCare – Clinic & Patient Management System (EHR) plugin for WordPress is vulnerable to generic SQL Injection via the 'orderby' parameter in all versions up to, and including, 4.5.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Doctor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires a KiviCare Doctor, Receptionist, or Clinic Admin role at minimum, as the vulnerable REST endpoint is restricted to authenticated users with custom plugin-level access.
Quick answer
KiviCare – Clinic & Patient Management System (EHR) should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.

How to fix it
KiviCare – Clinic & Patient Management System (EHR) is affected by CVE-2026-15073, a SQL injection issue in versions up to 4.5.0. Wordfence lists the official remediation as updating to version 4.5.1, or a newer patched version. Prioritize internet-facing WordPress sites, sites with public registration, customer portals, support, booking, import/export, page-builder, and admin workflows where the vulnerable feature is enabled. If immediate patching is not possible, disable the affected plugin or feature, restrict access, and monitor for exploitation until the update is installed.
- Inventory every WordPress site that has KiviCare – Clinic & Patient Management System (EHR) installed, including production, staging, multisite, client, WooCommerce, support, booking, and content-management environments.
- Confirm the installed KiviCare – Clinic & Patient Management System (EHR) version and compare it with the affected range from the Wordfence advisory.
- Update KiviCare – Clinic & Patient Management System (EHR) to version 4.5.1, or to a newer vendor-supported patched version from the official WordPress update channel.
- If the update cannot be applied immediately, disable KiviCare – Clinic & Patient Management System (EHR) or the affected feature and restrict access with roles, authentication, WAF rules, or temporary route blocking.
- Review database logs, application logs, suspicious queries, exported records, user accounts, orders, bookings, tickets, form entries, and configuration changes for evidence of data access or tampering.
- Rotate administrator sessions, API keys, webhook secrets, payment or integration tokens, and affected credentials if logs or content review suggest compromise.
- Clear WordPress, object, CDN, page-builder, security plugin, WooCommerce, booking/support plugin, and browser caches after patching so vulnerable assets or stored payloads are not served.
