Official description

Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Prior to version 2.53.0, an authenticated user could supply specially crafted content in certain user-editable fields that, when surfaced in page metadata, caused visitors' browsers to navigate to an attacker-chosen URL. This issue has been patched in version 2.53.0.
