The same applies to refresh tokens. This violates the RFC stipulations that 'The authorization server MUST invalidate the token.' and 'introspection of a revoked token MUST return {\"active\":false}'. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue."

Lo mismo se aplica a los tokens de actualización. Esto viola las estipulaciones de la RFC que establecen que ’El servidor de autorización DEBE invalidar el token.’ y ’la introspección de un token revocado DEBE devolver {“active”:false}’. Se recomienda a los usuarios actualizar a las versiones 4.2.3 o 4.1.8 o 3.6.12, que solucionan este problema."
