Description

Impact

It's possible to display any page you cannot access through the combination of the async and display macro.

Steps to reproduce:

Enable comments for guests by giving guests comment rights
As a guest, create a comment with content {{async}}{{display reference="Menu.WebHome" /}}{{/async}}
Open the comments viewer from the menu (appends ?viewer=comments to the URL)

-> the Menu.WebHome is displayed while the expectation would be to have an error that the current user is not allowed to see it
