Qualys is reporting this as a critical security issue. I am looking for an update for Microsoft Sync Framework 1.0 and the only thing I find is that if it was installed as a part of SharePoint 2016 is it supported beyond the EOL. If it is supported, is there an update available? I did find Microsoft Sync Framework 2.1 SDK that is newer but it doesn't appear that it will work with SharePoint 2016 Server.
