OAuth: Cross-origin token-request redirects can expose signed request metadata
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.

OAuth2::Client#request: Protocol-relative redirect Location overrides authority, leaking bearer Authorization to attacker host
OAuth2 is a Ruby wrapper for the OAuth 2.0 and 2.1 authorization frameworks, including OpenID Connect (OIDC). From 0.4.0 to 2.0.21, a protocol-relative redirect Location returned to OAuth2::Client#request overrides the request authority, so the bearer Authorization header is sent to an attacker-controlled host, leaking the credential. This issue is fixed in version 2.0.22.
