CVE-2026-5022
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe '/api/v1/files/images/{flow_id}/{file_name}' endpoint does not enforce any authentication or authorization checks, allowing any unauthenticated user to download images belonging to any flow by knowing (or guessing) the flow ID and file name.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe '/api/v1/files/images/{flow_id}/{file_name}' endpoint lacks authentication and authorization enforcement, allowing any unauthenticated user to access image files from any flow by simply knowing or guessing the flow ID and file name. This is an Insecure Direct Object Reference (IDOR) vulnerability combined with missing access control.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Langflow API is accessibleIdentify if Langflow is running and the API endpoint is reachable by checking open ports or service statusAffected if Langflow is running and the API is network-accessible
-
Test the image endpoint without authenticationSend a GET request to /api/v1/files/images/{flow_id}/{file_name} with any placeholder flow ID and file name, without including any authentication token, session cookie, or credentialsAffected if The request returns HTTP 200 or an image file instead of HTTP 401 or 403
-
Verify other endpoints require authenticationTest a different protected Langflow API endpoint (such as /api/v1/flows or /api/v1/users/me) without credentials to confirm authentication is normally enforcedAffected if Other endpoints correctly reject unauthenticated requests with 401/403, but the /api/v1/files/images endpoint does not
-
Attempt access with arbitrary flow IDsTry accessing different flow IDs at the image endpoint to confirm any flow's images can be retrieved without authorization checksAffected if Image files from any flow ID are accessible without proper authorization
If the /api/v1/files/images/{flow_id}/{file_name} endpoint returns image data without requiring authentication or authorization, the environment is affected by CVE-2026-5022.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper authentication and authorization checks on the endpoint to verify that the requesting user has permission to access the specific flow's images before serving the file.
