Descriptions

The HttpClient from Reactor Netty, versions 0.9.x prior to 0.9.5, and versions 0.8.x prior to 0.8.16, may be used incorrectly, leading to a credentials leak during a redirect to a different domain. In order for this to happen, the HttpClient must have been explicitly configured to follow redirects.

El HttpClient del Reactor Netty, versiones 0.9.x anteriores a 0.9.5, y versiones 0.8.x anteriores a 0.8.16, puede ser usado incorrectamente, conllevando a un filtrado de credenciales durante un redireccionamiento hacia un dominio diferente. A fin de que esto ocurra, el HttpClient debe haber sido configurado explícitamente para seguir los redireccionamientos.
