Frappe is a full-stack web application framework. Prior to 16.18.0, the Workspace Save API accepts a controlled workspace identifier from any authenticated user without enforcing workspace ownership, allowing modification of another user's private workspace and persistent script injection. This issue is fixed in version 16.18.0.
