The remote version of Serendipity is vulnerable to cross-site scripting
attacks due to a lack of sanity checks on the 'searchTerm' parameter in
the 'compat.php' script.  With a specially crafted URL, an attacker can
cause arbitrary code execution in a user's browser resulting in a loss
of integrity.
