CVE-2012-3387: Moodle

Medium severity, CVSS 4.0. EPSS: 1.1% chance of exploitation in the next 30 days.

Moodle 2.3.x before 2.3.1 uses only a client-side check for whether references are permitted in a file upload, which allows remote authenticated users to bypass intended alias (aka shortcut) restrictions via a client that omits this check.
