CVE-2026-31829

Flowise affected by Server-Side Request Forgery (SSRF) in HTTP Node Leading to Internal Network Access

State: Published
Severity: 7.1 High
Published: Mar 10, 2026
Updated: Mar 11, 2026
Reserved: Mar 9, 2026

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.
