CVE-2026-41279

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, the text-to-speech generation endpoint (POST /api/v1/text-to-speech/generate) is whitelisted (no auth) and accepts a credentialId directly in the request body. When called without a chatflowId, the endpoint uses the provided credentialId to decrypt the stored credential (e.g., OpenAI or ElevenLabs API key) and generate speech. 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 punto final de generación de texto a voz (POST /api/v1/text-to-speech/generate) está en la lista blanca (sin autenticación) y acepta un credentialId directamente en el cuerpo de la solicitud. Cuando se llama sin un chatflowId, el punto final utiliza el credentialId proporcionado para descifrar la credencial almacenada (por ejemplo, clave API de OpenAI o ElevenLabs) y generar voz. Esta vulnerabilidad se corrigió en la versión 3.1.0.
