Name of the Vulnerable Software and Affected Versions DNN (formerly DotNetNuke) versions prior to 10.1.0

Description DNN is an open-source web content management platform. Prior to version 10.1.0, arbitrary themes could be loaded through query parameters.

Depending on the vulnerability within a theme, this could lead to server-side or client-side arbitrary code execution.
