Hidden revisions are still visible on user's contribs pages. And therefore if there's a personal information in edit summaries it will be visible. Probably, page histories should be doublechecked too. Marking as major due to possible consequences.
I'm not able to reproduce this using current trunk versions of MediaWiki and Oversight...
This should be completely impossible. Oversighted revisions are removed from any part of the database read by any part of the software. They should only be recoverable manually. Perhaps you were seeing stale results or something. Could you link to the exact place you saw it?
Last time I saw it was yesterday: http://en.wikipedia.org/wiki/Special:Contributions/Nominal_GDP After David Gerrard zapped all edits, they continued to be visible despite several refreshes on my side. Clicking on all diffs produced 'no such revision' error. Today all is gone. I tried to reproduce this on testwiki and failed, but I'm pretty sure about yesterday. And no, my ISP does not use proxies or any other kind of caching.

Contribs pages were lagged, yes, as I suggested, because of some update scripts Brion was running on db6 (which serves contribs). It should be fixed either now or shortly, when updates are done.
