"The version of Mattermost Server installed on the remote host is prior to 9.5.10, 9.10.3, 9.11.2, 10.0.1 or 10.1.0. It
is, therefore, affected by a vulnerability as referenced in the MMSA-2024-00381 advisory.

  - Mattermost versions 9.10.x <= 9.10.2, 9.11.x <= 9.11.1, 9.5.x <= 9.5.9 and 10.0.x <= 10.0.0 fail to
    properly authorize the requests to /api/v4/channels which allows a User or System Manager, with Read
    Groups permission but with no access for channels to retrieve details about private channels that they
    were not a member of by sending a request to /api/v4/channels. (CVE-2024-42000)

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