## Technical details

The vulnerability is an improper authorization flaw (CWE-863) in multiple workflow endpoints across FlwInstanceController, FlwDefinitionController, FlwCategoryController, FlwSpelController, and TestLeaveController. The application performs coarse-grained role-based access control via @SaCheckPermission annotations but fails to implement fine-grained data-ownership verification at the service layer. An authenticated attacker with a functional permission (e.g., workflow:instance:query) can enumerate and access or modify any record by manipulating resource IDs (businessId, instanceId, definitionId) in request parameters, achieving horizontal privilege escalation across peer users. The attack requires authentication and network reachability to affected endpoints, but no additional preconditions.
