CVE-2026-54605

Descripción

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.
