      "value": "IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the disk-based caching mechanism. The AsyncDiskCache class uses Python's unsafe pickle.loads() function to deserialize cached objects from disk without validation, integrity verification, or authentication, enabling arbitrary code execution when malicious pickle payloads are processed. Attackers who can influence cached data through file system access, malicious workflow inputs, custom components, or API manipulation can achieve complete system compromise with the privileges of the Langflow server process."

      "value": "IBM Langflow OSS 1.0.0 hasta 1.10.0 contienen una crítica vulnerabilidad de ejecución remota de código en el mecanismo de caché basado en disco. La clase AsyncDiskCache utiliza la función insegura pickle.loads() de Python para deserializar objetos en caché desde el disco sin validación, verificación de integridad o autenticación, lo que permite la ejecución de código arbitrario cuando se procesan cargas útiles pickle maliciosas. Atacantes que pueden influir en los datos en caché a través del acceso al sistema de archivos, entradas de flujo de trabajo maliciosas, componentes personalizados o manipulación de la API pueden lograr un compromiso completo del sistema con los privilegios del proceso del servidor Langflow."
