CVE-2024-37146

Estado: ModificadaMedia (6.1)—

Flowise is a drag & drop user interface to build a customized large language model flow. In version 1.4.3 of Flowise, a reflected cross-site scripting vulnerability occurs in the `/api/v1/credentials/id` endpoint. If the default configuration is used (unauthenticated), an attacker may be able to craft a specially crafted URL that injects Javascript into the user sessions, allowing the attacker to steal information, create false popups, or even redirect the user to other websites without interaction.

Leer descripción completaMostrar menos

If the chatflow ID is not found, its value is reflected in the 404 page, which has type text/html. This allows an attacker to attach arbitrary scripts to the page, allowing an attacker to steal sensitive information. This XSS may be chained with the path injection to allow an attacker without direct access to Flowise to read arbitrary files from the Flowise server. As of time of publication, no known patches are available.

En la versión 1.4.3 de Flowise, se produce una vulnerabilidad de cross-site scripting reflejado en el endpoint `/api/v1/credentials/id`. Si se utiliza la configuración predeterminada (no autenticada), un atacante puede crear una URL especialmente manipulada que inyecta Javascript en las sesiones del usuario, lo que le permite robar información, crear ventanas emergentes falsas o incluso redirigir al usuario a otros sitios web sin interacción. Si no se encuentra el ID del flujo de chat, su valor se refleja en la página 404, que tiene el tipo texto/html.
