A vulnerability was found in Apache CloudStack 4.1.0 and 4.1.1, when calling the CloudStack API call listProjectAccounts as a regular, non-administrative user, the user is able to see information for accounts other than their own. References: http://seclists.org/oss-sec/2018/q1/1
JBoss Fuse does not use apache cloudstack and it's not affected by this flaw.
