Description

Matt Haggard reported that the statusText property of an XMLHttpRequest object is readable by the requestor even when the request is made across origins. This status information reveals the presence of a web server and could be used to gather information about servers on internal private networks. This issue was also independently reported to Mozilla by Nicholas Berthaume
