En resumen

Guzzle no elimina correctamente los encabezados Cookie sensibles cuando un sitio redirige a un dominio diferente o de HTTPS a HTTP, exponiendo tokens de autenticación y datos de sesión a servidores no confiables.

Detalle técnico

Al seguir redirecciones HTTP (respuestas 3xx) a un host diferente o al degradar de HTTPS a HTTP, Guzzle no elimina los encabezados Cookie añadidos manualmente antes de la solicitud de redirección, violando la política same-origin. Solo las cookies gestionadas por el middleware se eliminaban previamente. Los atacantes pueden inducir a las aplicaciones a enviar credenciales a dominios maliciosos mediante cadenas de redirección.

Resumen generado y traducido por IA a partir de la descripción oficial.
Guzzle is an open source PHP HTTP client. In affected versions the `Cookie` headers on requests are sensitive information. On making a request using the `https` scheme to a server which responds with a redirect to a URI with the `http` scheme, or on making a request to a server which responds with a redirect to a a URI to a different host, we should not forward the `Cookie` header on. Prior to this fix, only cookies that were managed by our cookie middleware would be safely removed, and any `Cookie` header manually added to the initial request would not be stripped. We now always strip it, and allow the cookie middleware to re-add any cookies that it deems should be there. Affected Guzzle 7 users should upgrade to Guzzle 7.4.4 as soon as possible. Affected users using any earlier series of Guzzle should upgrade to Guzzle 6.5.7 or 7.4.4. Users unable to upgrade may consider an alternative approach to use your own redirect middleware, rather than ours. If you do not require or expect redirects to be followed, one should simply disable redirects all together.
