How to fix?

A fix was pushed into the master branch but not yet published.


Dnn.Platform is an Open Source Web Application Framework.

Affected versions of this package are vulnerable to Privilege Escalation. For normal users, extra extension validation is performed at client-side only. Hence, a low privileged normal user can bypass the client-side validation and upload files with extensions which are allowed only for superuser only.
