JBoss BRMS 6 and BPM Suite 6 are vulnerable to a stored XSS via business process editor. The flaw is due to an incomplete fix for CVE-2016-5398. Remote, authenticated attackers that have privileges to create business processes can store scripts in them, which are not properly sanitized before showing to other users, including admins.

Cross-site scripting (XSS) vulnerability in Business Process Editor in Red Hat JBoss BPM Suite before 6.3.3 allows remote authenticated users to inject arbitrary web script or HTML by levering permission to create business processes.
