Summary
Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter implementation does not include a mechanism for validating access tokens, so by design when the HMAC signed cookie is missing a full authentication flow should be triggered. However, the current implementation assumes that access tokens are always validated thus allowing access in the presence of any access token attached to the request. Users are advised to upgrade. There is no known workaround for this issue.

En versiones anteriores a 1.22.1, la implementación del filtro OAuth no incluye un mecanismo para comprobar los tokens de acceso, por lo que, por diseño, cuando falta la cookie firmada por HMAC, debería desencadenarse un flujo de autenticación completo. Sin embargo, la implementación actual asume que los tokens de acceso son siempre comprobados, permitiendo así el acceso en presencia de cualquier token de acceso adjunto a la petición.
