What is CVE-2026-31829?

Flowise, a drag & drop user interface for building customized large language model flows, contains a vulnerability that exposes an HTTP Node in its AgentFlow and Chatflow functionalities. This issue allows for server-side HTTP requests to be made using user-controlled URLs without restrictions on target hosts, including internal IP ranges and cloud metadata endpoints. This poses a risk of Server-Side Request Forgery (SSRF), enabling potentially malicious users to access internal network resources that are normally inaccessible from the internet. This vulnerability was resolved in version 3.0.13.
