It's probably Radar, which is Apple's internal issue tracker, which isn't public (you can see issues you submitted, but nothing else). Sometimes people cross-post issues they submit to http://openradar.appspot.com, so you might be able to find it there.

That ID was likely for feedbackassistant.apple.com. However, those reports are not public, so you can't see them unless you're the one that reported them though. Knowing the ID is still useful for things like emailing Apple people and complaining about their declining software quality ;).

Looks like these issues are only visible to originator, so we have to trust the author about it. Perhaps the author could post it on the OpenRadar.
