The version of Mattermost Server installed on the remote host is prior to 9.5.7 or 9.9.1 / 9.10.0. It is, therefore, affected by a vulnerability as referenced in the MMSA-2024-00356 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
