It isn't; the input stream containing the multipart/form-data content
is passed to the CGI script, which can choose to parse it or not using
any code it has to hand - which could be the 'cgi' module, but not
necessarily.

Adam brings up a good point: eval is a very general function which
evaluates an arbitrary Python expression. As a result, it (and its
