I would expect bookmark listing to display my_bookmarks by default, similar to how the bookmark dropdown works.

I think you specifically mean other user's private bookmarks are visible, so updated. The page and public bookmarks should be accessible to any user.

Please report security issues first to foreman-security, don't just file them in Redmine. See http://theforeman.org/security.html and https://groups.google.com/forum/#!msg/foreman-dev/noN-XJ1qXgU/vYFPVYLQDQAJ for more information. I will forward and start the CVE process myself.

There are further related issues with bookmarks, mostly coming from resource_base not being adequately defined:

UI edit action can render a form for a private bookmark by ID, if the user has edit_permission.
API index and get responses also shows private bookmarks from other users
update and destroy actions of both the UI and API are not scoped to bookmarks that the user should have access to update, so they can supply an ID for a private bookmark of another user, the resource is found and updated. User needs edit/destroy_bookmarks permission for this.

I've requested a CVE for this issue, we'll address it in the next release(s) following a patch being written.

Depends on the permissions assigned to your "Anonymous" role, which is a minimum set applied to all users.

The default changed some time ago and view_hosts was removed. view_bookmarks is assigned by default, so ensure yours matches the default seed (db/seeds.d/03-roles.rb).
