Mahara 15.04 before 15.04.8 and 15.10 before 15.10.4 and 16.04 before 16.04.2 are vulnerable to a user - in some circumstances causing another user's artefacts to be included in a Leap2a export of their own pages.

Mahara 1.8 before 1.8.7 and 1.9 before 1.9.5 and 1.10 before 1.10.3 and 15.04 before 15.04.0 are vulnerable as logged-in users can stay logged in after the institution they belong to is suspended.

Mahara 1.8 before 1.8.6 and 1.9 before 1.9.4 and 1.10 before 1.10.1 and 15.04 before 15.04.0 are vulnerable to old sessions not being invalidated after a password change.

Mahara 1.9 before 1.9.7 and 1.10 before 1.10.5 and 15.04 before 15.04.2 are vulnerable to the arbitrary execution of Javascript in the browser of a logged-in user because the title of the portfolio page was not being properly escaped in the AJAX script that updates the Add/remove watchlist link on artefact detail pages.
