CVE-2026-33932 Details
Description
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, a stored cross-site scripting vulnerability in the CCDA document preview allows an attacker who can upload or send a CCDA document to execute arbitrary JavaScript in a clinician's browser session when the document is previewed. The XSL stylesheet sanitizes attributes for all other narrative elements but not for `linkHtml`, allowing `href="javascript:..."` and event handler attributes to pass through unchanged. Version 8.0.0.3 patches the issue.
A stored cross-site scripting vulnerability has been identified in OpenEMR versions prior to 8.0.0.3. This vulnerability allows an attacker to execute arbitrary JavaScript in a clinician's browser session by uploading or sending a CCDA document that is previewed. The issue arises because the XSL stylesheet used for sanitizing attributes in narrative elements does not properly handle 'linkHtml', allowing 'javascript:' links and event handler attributes to be injected. When the CCDA document is previewed, the unsanitized JavaScript executes in the context of the user viewing the document.
Users can update to OpenEMR version 8.0.0.3 or later, where this vulnerability has been patched.
