   * Advisory ID: DRUPAL-SA-CONTRIB-2015-169
   * Project: Chat Room [1]     (third-party module)
   * Version: 7.x
   * Date: 2015-December-02
   * Security risk: 11/25 ( Moderately Critical)
     AC:Complex/A:None/CI:Some/II:None/E:Theoretical/TD:Default [2]
   * Vulnerability: Access bypass

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

Chat Room enables site owners to integrate chats into nodes by adding the
chat room field to them. The module relies on a websocket connection to send
chat messages to the client.

The module doesn't sufficiently validate access before setting up the
websocket. As a result, users may receive messages from chat rooms they don't
have access to via the websocket.

   * /A CVE identifier [3] will be requested, and added upon issuance, in
     accordance with Drupal Security Team processes./

-------- VERSIONS AFFECTED

   * Chat Room 7.x-2.x versions prior to 7.x-2.2.

module, there is nothing you need to do.

-------- SOLUTION

Install the latest version:

   * If you use the Chat Room module for Drupal 7.x, upgrade to Chat Room
     7.x-2.2 [5]
