Descriptions

Elastic X-Pack Security versions 5.0.0 to 5.4.0 contain a privilege escalation bug in the run_as functionality. This bug prevents transitioning into the specified user specified in a run_as request. If a role has been created using a template that contains the _user properties, the behavior of run_as will be incorrect. Additionally if the run_as user specified does not exist, the transition will not happen.

Las versiones 5.0.0 hasta 5.4.0 de Elastic X-Pack Security contienen un error de escalación de privilegios en la funcionalidad run_as. Este error impide la transición al usuario establecido, especificado en una petición de run_as. Si un rol ha sido creado utilizando una plantilla que contiene las propiedades de _user, el comportamiento de run_as será incorrecto. Además, si el usuario run_as especificado no existe, la transición no se pasará.
