-------- DESCRIPTION
---------------------------------------------------------

*UPDATE (2017-07-12)*: This SA originally recommended version 2.6, but it was

the confusion!

DrupalChat allows visitors of your Drupal site to chat with each other
privately or together in a public chatroom.

The module did not confirm the validity of a chat request, resulting in a
Cross Site Request Forgery (CSRF) vulnerability which enables an attacker to
trick a user to send arbitrary chat messages to any user. The

The module did not filter administrator provided text, leading to a Cross
Site Scripting (XSS) vulnerability.
