CVE-2026-61644

FastGPT is a knowledge-based AI application platform. From 4.14.17 until 4.15.0-beta5, the POST /api/core/chat/record/getCollectionQuote endpoint authenticates the caller's chat and collection context, but the initialId center-node lookup is not bound to that authorized context. A low-privileged tenant user can call the endpoint with valid attacker-owned appId, chatId, chatItemDataId, and collectionId values while supplying another tenant's dataset data id as initialId, causing the response to include foreign dataset quote or full-text content. This issue is fixed in version 4.15.0-beta5.

Summary		(es) FastGPT es una plataforma de aplicación de IA basada en conocimiento. Desde la versión 4.14.17 hasta la 4.15.0-beta5, el endpoint POST /api/core/chat/record/getCollectionQuote autentica el contexto de chat y colección del llamador, pero la búsqueda del nodo central initialId no está vinculada a ese contexto autorizado. Un usuario inquilino con bajos privilegios puede llamar al endpoint con valores válidos de appId, chatId, chatItemDataId y collectionId propiedad del atacante, mientras suministra el ID de datos de un conjunto de datos de otro inquilino como initialId, lo que provoca que la respuesta incluya contenido de cita o texto completo de un conjunto de datos ajeno. Este problema está solucionado en la versión 4.15.0-beta5.
