DNN CKEditor Provider allows unauthenticated upload out-of-the-box
Summary
The out-of-box experience for HTML editing allows unauthenticated users to upload files. This opens a potential vector to other security issues and is not needed on most implementations.
Details
The new out-of-box experience blocks that endpoint to unauthenticated users. If there is a real need for the implementation to allow unauthenticated uploads, then the web.config can be edited by the implementer to remove that block and open the endpoint to the public.
