There are no known vulnerabilities in the DataAssist code itself. That doesn't mean you couldn't create a web page that is vulnerable though particularly if you are hand coding to make changes and updates after application.
If you track down the source of the vulnerability we would certainly be interested if it did happen in the DataAssist code, but I'm not aware of anything like that.
The first place to look would be in your use of File upload and HTML Editor fields with file management. Any time you give your users the ability to upload files to your web server it has the potential for misuse.
