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 flow_id and file_name 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&#39;s uploaded images without credentials. Version 1.9.0 contains a patch.</p> <p><strong>Affected:</strong> langflow-ai langflow</p> <p>Langflow is a tool for building and deploying AI-powered agents and workflows.

Any unauthenticated request with a known flow_id and file_name returns the image with HTTP 200.</p> <p>### Details `src/backend/base/langflow/api/v1/files.py:138-164` — `download_image` takes `flow_id`: UUID as a bare path parameter with no Depends(get_flow) or `CurrentActiveUser`. All other file routes (`download_file`, `upload_file`, `list_files`, `delete_file`) use `Depends(get_flow)` which enforces both authentication and ownership. There is no global auth middleware on /api/v1; protection is per-endpoint only.</p> <p>### PoC ``` curl -v &#34;http://localhost:7860/api/v1/files/images/&lt;flow_uuid&gt;/&lt;filename.png&gt;&#34; # Returns HTTP 200 with image bytes, no auth header required ```</p> <p>### Impact Unauthenticated cross-tenant data leak.
