Description
OAuth is a Ruby wrapper for the OAuth 1.0 and 1.0a protocols, providing clients and servers. From 0.5.5 to 1.1.5, OAuth::Consumer#token_request parses the raw Location header of a 300 to 399 redirect returned by the OAuth server and follows the redirect recursively, which can mutate the consumer's configuration and expose signed OAuth request metadata, including the Authorization header, to a cross-origin host. This issue is fixed in version 1.1.6.
