OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.1, the dynamic code picker AJAX endpoint returns code descriptions (code_text) that are rendered in the front end (e.g. DataTables) without HTML escaping.

If an administrator (or user with code management rights) creates or edits a code with a malicious description containing script, that script runs in the browser of every user who uses the picker. This vulnerability is fixed in 8.0.0.1.
