"Facebook spokesperson David Swain contacted us and confirmed that the appearance of unauthorized apps was a bug:
In this case, there was a bug that was showing applications on a user’s Application Settings page that the user hadn’t authorized. No information was shared with those applications and the user’s list of applications was not shown to anyone but the user. This bug has been fixed.
It does appear that unauthorized apps are no longer being added to users' pages, however any unwanted applications that were previously added will still need to be removed manually."
