Official description
ApostropheCMS is an open-source Node.js content management system. Prior to 4.32.0, the page module's move() operation fails to enforce the destination parent's _create permission because its oldParent archive condition disables the check for ordinary moves, allowing an authenticated editor or contributor to use _targetId and _position through the page REST update endpoint to move a controlled page into a restricted subtree and make nudgeNewPeers() updateMany re-rank protected sibling pages. This issue is fixed in version 4.32.0.
