Summary
Langflow has Unauthenticated IDOR on Image Downloads
Details

Langflow is a tool for building and deploying AI-powered agents and workflows. In versions 1.0.0 through 1.8.1, the /api/v1/files/images/{flow_id}/{file_name} endpoint serves image files without any authentication or ownership check. Any unauthenticated request with a known flowid and filename returns the image with HTTP 200. In a multi-tenant deployment, any attacker who can discover or guess a flow_id (UUIDs can be leaked through other API responses) can download any user's uploaded images without credentials. Version 1.9.0 contains a patch.
