CVE-2014-3863
Cross-site scripting (XSS) vulnerability in the JChatSocial component before 2.3 for Joomla! allows remote attackers to inject arbitrary web script or HTML via the filename parameter in a file upload in an active JChat chat window.
Does this matter?
Lower severity and a low EPSS score (1.92%). Track it; it rarely justifies an emergency change on its own.
