The KiviCare – Clinic & Patient Management System (EHR) plugin for WordPress is vulnerable to arbitrary file uploads due to missing authorization checks in the uploadMedicalReport() function in all versions up to, and including, 3.6.15. This makes it possible for unauthenticated attackers to upload text files and PDF documents to the affected site's server which may be leveraged for further attacks such as hosting malicious content or phishing pages via PDF files.
