3DescriptionGitHub Advisory
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.2, users with the Notes - my encounters role can fill Eye Exam forms in patient encounters. The answers to the form can be printed out in PDF form. An arbitrary file read vulnerability was identified in the PDF creation function where the form answers are parsed as unescaped HTML, allowing an attacker to include arbitrary image files from the server in the generated PDF. Version 8.0.0.2 fixes the issue.
Executive ViewAI
OpenEMR contains a remote code execution vulnerability (CVE-2026-33301, CVSS 8.1) that allows unauthenticated attackers to execute arbitrary code on healthcare systems. This directly threatens patient data confidentiality, system integrity, and operational continuity for any organization running vulnerable OpenEMR instances.
Apply vendor patch.
