GHSA-q559-8m2m-g699 Change in port should be considered a change in origin

• Packagist guzzlehttp/guzzle: < 6.5.8 → fixed in 6.5.8 • Packagist guzzlehttp/guzzle: >= 7.0.0, < 7.4.5 → fixed in 7.4.5

Impact `Authorization` and `Cookie` headers on requests are sensitive information. On making a request which responds with a redirect to a URI with a different port, if we choose to follow it, we should remove the `Authorization` and `Cookie` headers from the request, before containing. Previously, we would only consider a change in host or scheme downgrade. Now, we consider any change in host, port or scheme to be a change in origin. Patches Affected Guzzle 7 users should upgrade to Guzzle 7.4.5 as soon as possible. Affected users using any earlier series of Guzzle should upgrade to Guzzle 6.5.8 or 7.4.5. Workarounds An alternative approach would be to use your own redirect middleware, rather than ours, if you are unable to upgrade. If you do not require or expect redirects to be followed, one should simply disable redirects all together.
