We had difficulty implementing a fix for issue #3 in this bug's description: the export of pages that already include links to other users' artefacts. So since preventing the linking to other users' artefacts mitigates the risk of that vulnerability somewhat, I've gone ahead and spun that out into a separate bug: https://bugs.launchpad.net/mahara/+bug/1234615
