Guzzle is an open source PHP HTTP client. In affected versions
Authorization
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, we should not forward the Authorization
header on. This is much the same as to how we don’t forward on the header
if the host changes. Prior to this fix, https
to http
downgrades did
not result in the Authorization
header being removed, only changes to the
host. 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 which would be to use their own redirect middleware.
Alternately users may simply disable redirects all together if redirects
are not expected or required.
