## Overview

### 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This advisory has been withdrawn because it is a duplicate of GHSA-9hrv-gvrv-6gf2.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.

## Affected packages

- `flowise < 3.1.0`

## Remediation

Upgrade to a patched release:

- `flowise 3.1.0`
