In version 4.9.0, Chartbrew allows authenticated users with access to one project to update or delete a SharePolicy record that belongs to a different project. The affected routes authorize the caller against the project in the URL path, but they never verify that policy_id belongs to that project. This permits cross-project modification of dashboard sharing rules, including visibility, password requirements, allowed parameters, and expiration settings.
