Summary
A broken access control vulnerability in the BPM module of yudao-cloud before version 2026.06 allows any authenticated user to access arbitrary process instance records by supplying a caller-controlled process-instance identifier to an unprotected GET endpoint lacking the @PreAuthorize annotation. Attackers can read sensitive workflow data including submitted form variables, approver identities, approval and rejection comments, and process BPMN XML without ownership or tenant party verification.
Risk Assessment
The organization is at risk of leaking sensitive process data, including personal and business information, which may lead to data protection violations and loss of customer trust.
Recommendation
Immediately update yudao-cloud to version 2026.06 or later and add the @PreAuthorize annotation to the GET endpoint in the BPM module to enforce permission and ownership verification of process instances.
