A flaw was found in the BPMN editor. Any authenticated user from any project can see the name of Ruleflow Groups from other projects, despite the user not having access to those projects. The highest threat from this vulnerability is to confidentiality.
It was discovered that the XmlUtils class in jbpmmigration performs expansion of external parameter entities while parsing XML files. A remote attacker could use this flaw to read files accessible to the user running the application server and, potentially, perform other more advanced XML eXternal Entity (XXE) attacks.
