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.
