Security researcher Rafael Gieschke reported that file URIs dragged from a web page in Firefox to other software do not have their contents properly filtered before being passed to other programs, such as the local file manager. This can allow for the theft or manipulation of arbitrary local files if a user can be convinced to drag items from a malicious web page to other programs.
