Doc Text:	It was discovered that wget could disclose a user's IP address in an FTP session. If the FTP server does not offer support for the passive FTP mode, wget would automatically fall back to the active FTP mode, which could expose the client's IP address as part of the "PORT" command, even if wget was used in combination with an anonymizing proxy.

Description Adam Mariš 2015-09-08 08:44:44 UTC

User's IP address is exposed to the FTP server when automatically falling back from passive mode to active mode using PORT command. Wget is using normally passive mode, but this situation occurs when server rejects the PASV command. The real IP address is exposed even if client uses proxy server. Affected versions are <= 1.16.3.
