"The version of Mattermost Server running on the remote host is prior to 7.8.8, 7.9.x prior to 7.9.6 or 7.10.x prior to
7.10.4. It is, therefore, affected by multiple vulnerabilities:

 - Mattermost fails to sanitize post metadata during audit logging resulting in permalinks contents being
   logged. (CVE-2023-4108)

 - Mattermost fails to properly validate the requesting user permissions when updating a system admin,
   allowing a user manager to update a system admin's details such as email, first name and last name.
   (CVE-2023-4107)

 - Mattermost fails to check if the requesting user is a guest before performing different actions to public
   playbooks, resulting a guest being able to view, join, edit, export and archive public playbooks.
   (CVE-2023-4106)

 - Mattermost fails to delete the attachments when deleting a message in a thread allowing a simple user to
   still be able to access and download the attachment of a deleted message. (CVE-2023-4105)

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