CVE-2012-3397

lib/modinfolib.php in Moodle 2.0.x before 2.0.10, 2.1.x before 2.1.7, 2.2.x
before 2.2.4, and 2.3.x before 2.3.1 does not check for a group-membership

which allows remote authenticated users to bypass intended access
restrictions by selecting an activity that is configured for a group of
other users.
