Official description

Emlog is an open source website building system. In 2.6.13 and earlier, the admin backend user search module's keyword parameter from admin/user.php is processed with addslashes but not HTML-escaped before being rendered into the value attribute in admin/views/user.php, allowing reflected cross-site scripting in an administrator's backend session. No fixed version is currently identified.
