Severity ?
7.7 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
Summary
CURLOPT_HTTPAUTH option not cleared on change of origin
Details

Impact

Authorization headers on requests are sensitive information. 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, if we choose to follow it, we should remove the CURLOPT_HTTPAUTH and CURLOPT_USERPWD options before continuing, stopping curl from appending the Authorization header to the new request. Previously, we would only consider a change in host. 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. 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.

Workarounds

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 stream handler backend, rather than curl.
