The conditions in which this happens are if consumers of the http-client: 1. make an http request with an authorization header 2. that request leads to a redirect (302) and 3. the redirect url redirects to another domain or hostname Then the authorization header will get passed to the other domain. The problem is fixed in version 1.0.8.
