      "value": "The mem0 1.0.0 server lacks authentication and authorization controls for its memory deletion API endpoint (DELETE /memories). The endpoint allows unauthenticated users to delete memory records by specifying arbitrary user identifiers (e.g., user_id, run_id, agent_id) in the request query parameters. A remote attacker can exploit this by sending unauthenticated DELETE requests to erase memory data for any user, leading to unauthorized data loss and denial of service."

      "value": "El servidor mem0 1.0.0 carece de controles de autenticación y autorización para su endpoint de API de eliminación de memoria (DELETE /memories). El endpoint permite a usuarios no autenticados eliminar registros de memoria especificando identificadores de usuario arbitrarios (p. ej., user_id, run_id, agent_id) en los parámetros de consulta de la solicitud. Un atacante remoto puede explotar esto enviando solicitudes DELETE no autenticadas para borrar datos de memoria de cualquier usuario, lo que lleva a una pérdida de datos no autorizada y denegación de servicio."
