[#32825] Front End: Scheduled Articles are showing up on Contacts/Articles page

This is a minor security issue.
To test, create a few articles as superuser and define publish_up and/or publish_down for some of them.
Create a contact for the superuser with param Show articles.
Display the contact in frontend.
