therefore, affected by an incorrect authorization vulnerability. Mattermost fails to properly validate permissions when
demoting and deactivating a user allowing for a system/user manager to demote / deactivate another manager.

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