IBM Langflow OSS 1.0.0 through 1.10.3 does not properly validate ownership in the deprecated POST /api/v1/build/{flow_id}/vertices endpoint, allowing an authenticated user to inject arbitrary graph data into a shared cache for any flow. This may result in cross-user cache pollution, unauthorized workflow execution, or denial of service.
