"The version of Mattermost Server running on the remote host is prior to 7.1.4, 7.2.x prior to 7.2.1, or 7.3.x prior to
7.3.1. It is, therefore, affected by a denial of service (DoS) vulnerability. An authenticated, remote attacker can
crash the server via multiple large requests to one of the Playbooks API endpoints.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
