Descriptions

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. In the default configuration (unauthenticated), arbitrary origins may be able to make requests to Flowise, stealing information from the user. 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. As of time of publication, no known patches are available.

Flowise es una interfaz de usuario de arrastrar y soltar para crear un flujo de modelo de lenguaje grande personalizado. En la versión 1.4.3 de Flowise, una mala configuración de CORS establece el encabezado Access-Control-Allow-Origin en todos, lo que permite que orígenes arbitrarios se conecten al sitio web. En la configuración predeterminada (no autenticado), orígenes arbitrarios pueden realizar solicitudes a Flowise, robando información del usuario. Esta configuración errónea de CORS puede estar encadenada con la inyección de ruta para permitir que un atacante sin acceso a Flowise lea archivos arbitrarios del servidor Flowise. Al momento de la publicación, no hay parches conocidos disponibles.
