CVE-2011-4582
Open redirect vulnerability in the Calendar set page in Moodle 2.1.x before 2.1.3 allows remote authenticated users to redirect users to arbitrary web sites and conduct phishing attacks via a redirection URL.
Does this matter?
Lower severity and a low EPSS score (1.19%). Track it; it rarely justifies an emergency change on its own.
