CVE-2026-41266

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, /api/v1/public-chatbotConfig/:id ep exposes sensitive data including API keys, HTTP authorization headers and internal configuration without any authentication. An attacker with knowledge just of a chatflow UUID can retrieve credentials stored in password type fields and HTTP headers, leading to credential theft and more. This vulnerability is fixed in 3.1.0.

Summary		(es) Flowise es una interfaz de usuario de arrastrar y soltar para construir un flujo personalizado de modelo de lenguaje grande. Antes de la versión 3.1.0, el endpoint /api/v1/public-chatbotConfig/:id expone datos sensibles, incluyendo claves API, encabezados de autorización HTTP y configuración interna, sin ninguna autenticación. Un atacante con solo el conocimiento de un UUID de chatflow puede recuperar credenciales almacenadas en campos de tipo contraseña y encabezados HTTP, lo que lleva al robo de credenciales y más. Esta vulnerabilidad se corrige en la versión 3.1.0.
