The Calendar module in Liferay DXP does not escape user supplied data in the default notification email template, which allows remote authenticated users to inject arbitrary web script or HTML via the title of a calendar event or the user's name. This may lead to a content spoofing or cross-site scripting (XSS) attacks depending on the capability of the receiver's mail client. This issue is caused by an incomplete fix in LSV-557.
