Official description
Frappe is a full-stack web application framework. Prior to 16.19.0 and 15.109.0, Data Import does not escape imported column headers before rendering previews and results, allowing an authenticated importer to persist script content that executes when another user views the import interface. This issue is fixed in versions 16.19.0 and 15.109.0.
