  "description": "HTTP::Tiny versions before 0.095 for Perl forward credential headers to cross-origin redirect targets.  When the server returns a 3xx redirect, \u0060_maybe_redirect\u0060 follows the \u0060Location:\u0060 header and \u0060_prepare_headers_and_cb\u0060 re-merges the caller\u0027s \u0060headers\u0060 argument into the new request, without checking whether the redirect target shares an origin with the original URL. Caller-supplied \u0060Authorization\u0060, \u0060Cookie\u0060 and \u0060Proxy-Authorization\u0060 headers are therefore re-sent to whatever host the redirect names, across scheme, host or port boundaries, and including \u0060https\u0060 to \u0060http\u0060 downgrades that expose them in plaintext on the wire.  The HTTP::Tiny POD note that \u0022Authorization headers will not be included in a redirected request\u0022 applied only to the URL-userinfo Basic-auth path, not to headers passed explicitly by the caller.",
