CVE-2026-58448Public exploitNetwork attack vector

Authenticated workflow disclosure via missing endpoint authorization

Published Jun 30, 2026 · Updated Jun 30, 2026

Missing authorization in the BPM module of YunaiV yudao-cloud before 2026.06 allows remote authenticated users to read workflow records. The get-bpmn-model-view endpoint omits @PreAuthorize, and its service trusts a caller-supplied process-instance ID without ownership or party checks. Any signed-in account with a valid ID can retrieve submitted form data, approver identities and comments, process state, and BPMN XML.
