CVE-2026-41278

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, the GET /api/v1/public-chatflows/:id endpoint returns the full chatflow object without sanitization for public chatflows. Docker validation revealed this is worse than initially assessed: the sanitizeFlowDataForPublicEndpoint function does NOT exist in the released v3.0.13 Docker image. Both public-chatflows AND public-chatbotConfig return completely raw flowData including credential IDs, plaintext API keys, and password-type fields. This vulnerability is fixed in 3.1.0.

Summary		(es) Flowise es una interfaz de usuario de arrastrar y soltar para construir un flujo de modelo de lenguaje grande personalizado. Antes de la versión 3.1.0, el endpoint GET /API/v1/public-chatflows/:id devuelve el objeto completo del chatflow sin sanitización para los chatflows públicos. La validación de Docker reveló que esto es peor de lo evaluado inicialmente: la función sanitizeFlowDataForPublicEndpoint NO existe en la imagen Docker v3.0.13 publicada. Tanto public-chatflows como public-chatbotConfig devuelven datos de flujo (flowData) completamente sin procesar, incluyendo IDs de credenciales, claves API en texto plano y campos de tipo contraseña. Esta vulnerabilidad está corregida en la versión 3.1.0.
