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. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /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. Drupal core is not affected.
