"Google Project Zero reports :

The transmission bittorrent client uses a client/server architecture,
the user interface is the client which communicates to the worker
daemon using JSON RPC requests.

As with all HTTP RPC schemes like this, any website can send requests
to the daemon listening on localhost with XMLHttpRequest(), but the
theory is they will be ignored because clients must prove they can
read and set a specific header, X-Transmission-Session-Id.
Unfortunately, this design doesn't work because of an attack called
'DNS rebinding'. Any website can simply create a dns name that they
are authorized to communicate with, and then make it resolve to
localhost.

Exploitation is simple, you could set script-torrent-done-enabled and
run any command, or set download-dir to /home/user/ and then upload a
torrent for .bashrc."
