DESCRIPTION:
Thomas Pollet has discovered a vulnerability in Clever Copy, which
can be exploited by malicious people to conduct script insertion
attacks.

Input passed to the Subject field in the Private Messages
functionality isn't sanitised before being stored. This can be
exploited to execute arbitrary script code in a user's browser
session in context of an affected website when a malicious message is
viewed.

The vulnerability has been confirmed in version 3.0. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
