Summary

CVE-2026-31829 affects Flowise before 3.0.13. Its HTTP Node in AgentFlow and Chatflow makes server-side HTTP requests to user-controlled URLs, with no default restrictions on private or internal IP ranges (RFC 1918), localhost, or cloud metadata endpoints. Any user interacting with a publicly exposed chatflow can thus force the server to reach internal network resources.

Mitigation

Fixed in 3.0.13.
