Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2025-43860 impacting open-emr openemr. Evaluated with CVSS Base Score of 7.6 (HIGH).

Original NVD Description

Source: NIST NVD
OpenEMR is a free and open source electronic health records and medical practice management application. A stored cross-site scripting (XSS) vulnerability in versions prior to 7.0.3.4 allows any authenticated user with patient creation and editing privileges to inject arbitrary JavaScript code into the system by entering malicious payloads in the (1) Text Box fields of Address, Address Line 2, Postal Code and City fields and (2) Drop Down menu options of Address Use, State and Country of the Additional Addresses section of the Contact tab in Patient Demographics. The injected script can execute in two scenarios: (1) dynamically during form input, and (2) when the form data is later loaded for editing. Version 7.0.3.4 contains a patch for the issue.
