The HttpRequest object allows to get the HTTP headers from the servers response after sending the request. The problem is that the returned strings are created directly from the data returned by the server and are not correctly encoded for JavaScript. This allows to create internal strings that can be used to access hidden properties of objects.
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
