CVE-2013-4940 describes a cross-site scripting (XSS) vulnerability in the io.swf component of Yahoo! YUI 3.10.2, which is widely used in products like Moodle versions through 2.1.10, 2.2.x before 2.2.11, 2.3.x before 2.3.8, 2.4.x before 2.4.5, and 2.5.x before 2.5.1. This flaw allows remote attackers to inject arbitrary web script or HTML via a crafted URL, stemming from a regression of CVE-2013-4939. With a CVSS score of 4.3 (medium severity), it requires medium attack complexity and could lead to information disclosure or defacement, but not full system compromise.
