Description

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to version 10.1.0, when embedding information in the Biography field, even if that field is not rich-text, users could inject javascript code that would run in the context of the website and to any other user that can view the profile including administrators and/or superusers. This issue has been patched in version 10.1.0.
