CVE-2026-54601

FastGPT is an open source AI knowledge base platform. From 4.14.17 to before 4.15.0-beta4, FastGPT allows an authenticated tenant user to call POST /api/core/dataset/collection/create/reTrainingCollection in a way that persists a server-owned datasetId value from another tenant. This creates mixed dataset objects and downstream dataset, collection, and training endpoints then make authorization decisions from inconsistent ownership anchors, allowing cross-tenant read, update, and delete access when mixed object ids are known. This issue is fixed in version 4.15.0-beta4.

Summary		(es) FastGPT es una plataforma de base de conocimiento de IA de código abierto. Desde la versión 4.14.17 hasta antes de la 4.15.0-beta4, FastGPT permite a un usuario de inquilino autenticado llamar a POST /API/core/dataset/collection/create/reTrainingCollection de una manera que persiste un valor de datasetId propiedad del servidor de otro inquilino. Esto crea objetos de conjunto de datos mixtos y los puntos finales de conjunto de datos, colección y entrenamiento posteriores luego toman decisiones de autorización a partir de anclajes de propiedad inconsistentes, permitiendo acceso de lectura, actualización y eliminación entre inquilinos cuando se conocen los ID de objetos mixtos. Este problema está solucionado en la versión 4.15.0-beta4.
