Description

Flowise is a drag & drop user interface to build a customized large language model flow. In version 1.4.3 of Flowise, A CORS misconfiguration sets the Access-Control-Allow-Origin header to all, allowing arbitrary origins to connect to the website.

This CORS misconfiguration may be chained with the path injection to allow an attacker attackers without access to Flowise to read arbitrary files from the Flowise server.
