A flaw was found in the BPMN editor in version jBPM 7.51.0.Final. 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 6.5 performed 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.

Multiple cross-site scripting (XSS) vulnerabilities in JBPM KIE Workbench 6.0.x allow remote authenticated users to inject arbitrary web script or HTML via vectors related to task name html inputs.

XML external entity (XXE) vulnerability in Drools and jBPM before 6.2.0 allows remote attackers to read arbitrary files or possibly have other unspecified impact via a crafted BPMN2 file.

XML external entity (XXE) vulnerability in the JBPMBpmn2ResourceImpl function in designer/bpmn2/resource/JBPMBpmn2ResourceImpl.java in jbpm-designer 6.0.x and 6.2.x allows remote attackers to read arbitrary files and possibly have other unspecified impact by importing a crafted BPMN2 file.

A regression error in the embedded HSQLDB in JBoss jBPM 2.0 allows remote attackers to execute arbitrary comands, a re-introduction of a vulnerability that was originally identified by CVE-2003-0845.
