Umbraco Commerce is an open source dotnet web forms solution. In affected versions an authenticated user that has access to edit Forms may inject unsafe code into Forms components. This issue can be mitigated by configuring TitleAndDescription:AllowUnsafeHtmlRendering after upgrading to one of the patched versions (13.0.1, 12.2.2, 10.5.3, 8.13.13).
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
