En XWiki 16.10.0, se introdujeron los permisos obligatorios para limitar los permisos que puede tener un documento. Parte del modelo de seguridad de los permisos obligatorios consiste en que un usuario sin permisos tampoco puede definirlos como obligatorios. De esta forma, los usuarios que editan documentos con permisos obligatorios pueden estar seguros de no otorgar permisos a un script u objeto que no pose\u00edan previamente. Un error en la implementaci\u00f3n de esta regla permiti\u00f3 que cualquier usuario con permisos de edici\u00f3n en un documento pudiera establecer permisos de programaci\u00f3n como obligatorios. Si un usuario con permisos de programaci\u00f3n editaba ese documento, el contenido obten\u00eda permisos de programaci\u00f3n, lo que permit\u00eda la ejecuci\u00f3n remota de c\u00f3digo. Esto anula la mayor\u00eda de las ventajas de seguridad de los permisos obligatorios.
