- Details
-
HTTP::Tiny versions before 0.095 for Perl forward credential headers to cross-origin redirect targets.
When the server returns a 3xx redirect,
_maybe_redirectfollows theLocation:header and_prepare_headers_and_cbre-merges the caller'sheadersargument into the new request, without checking whether the redirect target shares an origin with the original URL. Caller-suppliedAuthorization,CookieandProxy-Authorizationheaders are therefore re-sent to whatever host the redirect names, across scheme, host or port boundaries, and includinghttpstohttpdowngrades that expose them in plaintext on the wire.The HTTP::Tiny POD note that "Authorization headers will not be included in a redirected request" applied only to the URL-userinfo Basic-auth path, not to headers passed explicitly by the caller.
