      "value": "Incorrect Authorization (CWE-863) in Kibana can lead to integrity compromise of Machine Learning audit and notification records via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1).\n\nA vulnerability exists in Kibana's Machine Learning functionality where a Machine Learning management endpoint performs an insufficient authorization check. The endpoint validates only a coarse privilege level but does not verify that the requesting user has access to the specific Machine Learning job or notification resources provided in the request. As a result, a low-privileged user with Machine Learning access in any Kibana space can manipulate Machine Learning audit and notification records for arbitrary jobs—including jobs in other spaces or belonging to other users—by leveraging Kibana's internally elevated credentials to write to restricted Machine Learning system indices that the user cannot access directly."

      "value": "Autorización Incorrecta (CWE-863) en Kibana puede llevar al compromiso de la integridad de los registros de auditoría y notificación de Machine Learning a través del Acceso a Funcionalidad No Restringida Adecuadamente por ACLs (CAPEC-1).\n\nExiste una vulnerabilidad en la funcionalidad de Machine Learning de Kibana donde un endpoint de gestión de Machine Learning realiza una verificación de autorización insuficiente. El endpoint valida solo un nivel de privilegio general pero no verifica que el usuario solicitante tenga acceso a los recursos específicos de trabajo o notificación de Machine Learning proporcionados en la solicitud. Como resultado, un usuario con privilegios bajos con acceso a Machine Learning en cualquier espacio de Kibana puede manipular los registros de auditoría y notificación de Machine Learning para trabajos arbitrarios -incluyendo trabajos en otros espacios o que pertenecen a otros usuarios- aprovechando las credenciales internamente elevadas de Kibana para escribir en índices de sistema de Machine Learning restringidos a los que el usuario no puede acceder directamente."
