ssh with X11 forwarding (-X option) had this same problem. A privileged malicious user on the host you were ssh'ed into might be able to monitor the keystrokes of your whole X session.

'-X' is supposedly the safe alternative to '-Y'. However, as a Cygwin/X maintainer says "this is widely considered to be not useful, because the Security extension uses an arbitrary and limited access control policy, which results in a lot of applications not working correctly and what is really a false sense of security"
