Technical details

A broken access control vulnerability exists in the BPM module of yudao-cloud due to a missing authorization check. Specifically, the 'get-bpmn-model-view' endpoint in BpmProcessInstanceController.java lacks the @PreAuthorize annotation used by other endpoints in the same controller. An authenticated attacker can exploit this by sending a GET request to '/bpm/process-instance/get-bpmn-model-view' with a specific process-instance ID. This allows the retrieval of sensitive data including form variables, approver identities, rejection comments, and BPMN XML definitions without ownership or tenant verification. The vulnerability is addressed in version 2026.06.
