Summary: On Tableau Server, the administrative view, ‘‘Who has seen this view?,’’ is a link that is displayed to users who publish views. The underlying URL can be manipulated to disclose metadata for all workbooks on the current site, regardless of the current user’s permissions.
Impact: Any Tableau Server user who has View role can construct a URL to view the usernames, sheet names, and view counts for workbooks on the current site.
