Foreman 1.5.0 or higher are vulnerable to an authorization issue that allows users to view and delete reports for hosts that they don't have access to.

Reports (from tools such as Puppet) are stored in Foreman and associated to the host they came from. Users can be granted permissions to view and/or destroy reports, and also separate permissions to view certain hosts. The UI and API only list reports where the user has permission to view both reports and the host it was from.

The security issue is that both the show and destroy actions for viewing and deleting individual reports do not limit access to the hosts that the user has permission to view. A user with permission to view or destroy reports can do so for any host if they know the ID, or can easily view the last report for a given host.
