En versiones anteriores a 6.4.12, las peticiones autenticadas al servidor del cuaderno con \"ContentsManager.allow_hidden = False\" s\u00f3lo imped\u00edan listar el contenido de los directorios ocultos, no acceder a archivos individuales ocultos o a los archivos de directorios ocultos (es decir, los archivos ocultos estaban \"ocultos\" pero no \"inaccesibles\"). Esto podr\u00eda conllevar a que las configuraciones de los ordenadores port\u00e1tiles permitieran el acceso autenticado a archivos que razonablemente fueran esperados a que no estuvieran permitidos. Dado que son requeridas peticiones totalmente autenticadas, esto presenta un impacto relativamente bajo. Pero si el directorio root de un servidor contiene archivos confidenciales cuya \u00fanica protecci\u00f3n frente al servidor es estar oculto (por ejemplo, \"~/.ssh\" mientras sirve $HOME), entonces cualquier petici\u00f3n autenticada podr\u00eda acceder a los archivos si sus nombres son adivinables. Tales contextos tambi\u00e9n presentan necesariamente acceso completo al servidor y, por lo tanto, permisos de ejecuci\u00f3n, lo que generalmente tambi\u00e9n otorga acceso a todos los mismos archivos. Por lo tanto, esto no suele resultar en una escalada de privilegios o a un aumento del acceso a la informaci\u00f3n, sino a un medio adicional e involuntario por el que podr\u00eda accederse a los archivos.
