Summary

Flowable flowable-engine through 8.0.0 contains an XML external entity injection vulnerability in ProcessDiagramLayoutFactory.parseXml() that fails to disable external entity resolution when parsing deployed BPMN resources. Attackers with process deployment privileges can embed DOCTYPE declarations with external entities in BPMN files to read arbitrary local files or trigger requests to internal network endpoints when diagram layout is computed.

Risk Assessment

An attacker can exploit XXE to read sensitive files from the server or conduct attacks on internal network resources, potentially leading to data leakage or privilege escalation.

Recommendation

Update Flowable to a version newer than 8.0.0 that includes a fix disabling external XML entities.
