Description
IRIS is a web collaborative platform that helps incident responders share technical details during investigations. In versions prior to 2.4.28, users can create alerts for customers that are not assigned to them. This can be abused to falsely attribute fake alerts to customers. In combination with Cross-Site Scripting, this can also be used to exfiltrate alerts from other customers. Version 2.4.28 contains a patch.
