Description Andrej Nemec 2016-12-21 09:22:07 UTC
I was discovered that on sites with the git and recentchanges
plugins and the CGI interface enabled, the revert links on the
RecentChanges page could revert changes on a page the logged-in user
cannot legitimately edit, if the change being reverted was made before
the page was renamed from a location that the logged-in user *could*
legitimately edit.
