Description

Guzzle, an extensible PHP HTTP client. Authorization headers on requests are sensitive information. In affected versions when using our Curl handler, it is possible to use the CURLOPT_HTTPAUTH option to specify an Authorization header. On making a request which responds with a redirect to a URI with a different origin (change in host, scheme or port), if we choose to follow it, we should remove the CURLOPT_HTTPAUTH option before continuing, stopping curl from appending the Authorization header to the new request. 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. Note that a partial fix was implemented in Guzzle 7.4.2, where a change in host would trigger removal of the curl-added Authorization header, however this earlier fix did not cover change in scheme or change in port. If you do not require or expect redirects to be followed, one should simply disable redirects all together. Alternatively, one can specify to use the Guzzle steam handler backend, rather than curl.
