How to fix?

Upgrade guzzlehttp/guzzle to version 6.5.8, 7.4.5 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. When Curl handler is in use, the Authorization header can be included in a request that was redirected to a URI with a different origin. By exploiting this vulnerability it is possible to expose these headers to the URI that the request is being redirected towards.

Workarounds:

If you do not require or expect redirects to be followed, one should simply disable redirects altogether. Alternatively, one can specify to use the Guzzle stream handler backend, rather than curl.
