+	  <p>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.</p>
+	  <p>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.</p>
+	  <p>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.</p>
