CVE-2026-33301 Details
Description
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.
A vulnerability allowing arbitrary file read has been identified in OpenEMR versions prior to 8.0.0.2. This issue arises in the PDF creation function of the Eye Exam form, where user responses are processed as unescaped HTML. As a result, an attacker can inject image files from the server into the generated PDF. Additionally, there is a high likelihood that this vulnerability could be exploited to read other types of files by manipulating PHP filter chains.
Users can update to OpenEMR version 8.0.0.2 or later, where this vulnerability has been fixed.
