Title
Flowise - Server-Side Request Forgery via Execute Flow Base URL
Summary
Flowise before 3.1.0 contains a server-side request forgery vulnerability in the Execute Flow node that allows attackers to bypass security validation by providing intranet addresses through the base URL field. Attackers can initiate HTTP requests to internal network addresses, access cloud metadata, and enumerate internal services by exploiting the missing secureFetch verification in httpSecurity.ts.

GHSA-9HRV-GVRV-6GF2
Vulnerability from github – Published: 2026-04-16 21:23 – Updated: 2026-09-23 21:24
VLAI
Summary
Flowise Execute Flow function has an SSRF vulnerability
Details
Summary
The attacker provides an intranet address through the base url field configured in the Execute Flow node → Bypass checkDenyList / resolveAndValidate in httpSecurity.ts (not called) → Causes the server to initiate an HTTP request to any internal network address, read cloud metadata, or detect internal network services
Details
Then initiate the call:
POST /api/v1/prediction/d6739838-d3b3-43d9-86ff-911a3d757a7e HTTP/1.1
Host: 127.0.0.1:3000
Content-Type: application/json
Authorization: Bearer apikey
Content-Length: 17
{"question": "1"}
Server received a request:
And there is an echo:
Fix: Call secureFetch for verification
Impact
This is a Server-Side Request Forgery (SSRF) vulnerability that may lead to the following risks: - Explore Internal Web Applications - Access sensitive management interfaces - Leak internal configuration, credentials, or confidential information
This vulnerability significantly increases the risk of internal service enumeration and potential lateral movement in enterprise environments.

Summary
Duplicate Advisory: Flowise Execute Flow function has an SSRF vulnerability
Details
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-9hrv-gvrv-6gf2. This link is maintained to preserve external references.
Original Description
Flowise before 3.1.0 contains a server-side request forgery vulnerability in the Execute Flow node that allows attackers to bypass security validation by providing intranet addresses through the base URL field. Attackers can initiate HTTP requests to internal network addresses, access cloud metadata, and enumerate internal services by exploiting the missing secureFetch verification in httpSecurity.ts.
