Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Mattermost Server installed on the remote host is 9.11.x prior to 9.11.6, 10.0.x prior to 10.0.4, 10.1.x prior to 10.1.4, or 10.2.x prior to 10.2.1. It is, therefore, affected by a denial of service vulnerability due to a failure to properly validate post props which allows a malicious authenticated user to cause a crash via a malicious post.
