DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to 10.1.1, 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. This vulnerability is fixed in 10.1.1.

GHSA-2374-6cvw-qmx6 — DNN CKEditor Provider allows unauthenticated upload out-of-the-box

Affected: NuGet: Dnn.Platform

### 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.
