Description
OpenEMR before 8.5.0 contains a stored cross-site scripting vulnerability that allows portal patients to run JavaScript in staff sessions by injecting javascript: URLs into document template_data. Attackers can submit an encounterForm value rendered unsanitized into an iframe src by DocumentTemplateRender, letting the script read PHI and CSRF tokens and call staff or admin endpoints.
