Detailsinfo

A vulnerability was found in FlowiseAI Flowise up to 3.0.12. It has been declared as critical. Affected by this vulnerability is an unknown code block of the component HTTP Request Handler. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

It is possible to read the advisory at github.com. This vulnerability is known as CVE-2026-31829 since 03/09/2026. The exploitation appears to be difficult. The attack can be launched remotely. The technical details are unknown and an exploit is not publicly available.
