CVE-2012-3392 - Evasive Pencil

Description

mod/forum/unsubscribeall.php in Moodle 2.1.x before 2.1.7 and 2.2.x before 2.2.4 does not consider whether a forum is optional which allows remote authenticated users to bypass forum-subscription requirements by leveraging the student role and unsubscribing from all forums.
