A flaw was found in mediawiki. The “undo” feature (action=edit&undo;=##&undoafter;=###) allowed an attacker to view the contents of arbitrary revisions, regardless of whether they had permissions to do so. This was also found in the “mcrundo” and “mcrrestore” actions (action=mcrundo and action=mcrrestore).
