Adding a user to a Hub will allow them to view all files in the Hub regardless of permissions attributed to the files. However, Box Hubs will respect Box Shield access restrictions on content that is shared externally (in Beta). If there is a file or folder that has a Shield access policy AND that file or folder is in a Hub, then the restriction is applied when an external user tries to view the content.

A user can be invited to a Hub as an ‘Editor’ or a ‘Viewer.’ Editors can edit content within the Hub whereas Viewers can view, but not edit, the contents of the Hub. If a user does not have access to a file that has been added to a Hub, and the user is added to the Hub, they will receive ‘view’ access to the file. If a user has not been given Editor or Viewer permissions to a Hub they will not see files or folders in the Hub unless they have been added as a collaborator on that file or folder.
