The Ultimate Table Field module enables you to store table data in a field and edit each table cell through a dialog, using cell field plugins such as text, link, and file.

The module doesn't sufficiently protect the route that opens the cell editor dialog. The route is accessible to anonymous users, who can open the dialog for any cell type. The dialog allows uploading files to the server location.

This vulnerability is partially mitigated by the fact that only files with the pdf, doc and docx extensions are accepted.
