Executive brief
Dromara RuoYi-Vue-Plus is a business workflow and permission management system. An authenticated user with a given role can access or modify workflow instances, definitions, categories, and other sensitive data belonging to other users by directly manipulating resource identifiers in API requests, bypassing data-ownership checks.
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.
