autoload/netrw.vim (aka the Netrw Plugin) 109 131 and other versions before 133k for Vim 7.1.266 other 7.1 versions and 7.2 stores credentials for an FTP session and sends those credentials when attempting to establish subsequent FTP sessions to servers on different hosts which allows remote FTP servers to obtain sensitive information in opportunistic circumstances by logging usernames and passwords. NOTE: the upstream vendor disputes a vector involving different ports on the same host stating \I'm assuming that they're using the same id and password on that unchanged hostname deliberately.\
