You should definitely upgrade FCKeditor as version 2.2 has been release two years ago and some few security related issues have been fixed in the mean time.
Even if you decide to not upgrade immediately, you should at least replace the "editor/filemanager" folder, which contains the File Manager. Being the File Manager a server application, it is the only part of the code that could bring security concerns.
For version 2.5, there are no known security holes.
