Macromedia Contribute and worldwritable folders

when using contribute 3 to connect using sftp to a unix account, Contribute
creates directories which are world writeable if the umask is set to 077.
This a problem, why does contribute do this. Are there any plans to fix it?
I know that if I change the umask I can fix it but this shouldn't happen.
This measn that contribute users could inadvertantly create directories that
are worldreadable and compromise security.

Does anyone have any views/solutions/suggestions?
