CVE-2024-36423: Flowise reflected cross-site scripting via /api/v1/public-chatflows/id endpoint

Summary

CVE-2024-36423 affects Flowise version 1.4.3, where a reflected cross-site scripting flaw exists in the `/api/v1/public-chatflows/id` endpoint. With the default unauthenticated configuration, an attacker can craft a URL that injects JavaScript into user sessions to steal information, display false popups, or redirect users without interaction. The chatflow ID is reflected in a text/html 404 page when not found, and this XSS may be chained with path injection to read arbitrary files from the Flowise server.
