Title
Langflow OSS is affected by arbitrary code execution in custom component validation and trusted code enforcement
Summary
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.
