A flaw was found in mediawiki. The “mcrundo” and “mcrrestore” actions (action=mcrundo and action=mcrrestore) did not properly check for editing permissions and allowed an attacker to take the content of any arbitrary revision and save it on any page of their choosing. This affects both public wikis and public pages on private wikis.
