CVE-2022-31042— Failure to strip the Cookie header on change in host or HTTP downgrade in Guzzle

Failure to strip the Cookie header on change in host or HTTP downgrade in Guzzle

Guzzle is an open source PHP HTTP client. In affected versions the `Cookie` 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, or on making a request to a server which responds with a redirect to a a URI to a different host, we should not forward the `Cookie` header on. Prior to this fix, only cookies that were managed by our cookie middleware would be safely removed, and any `Cookie` header manually added to the initial request would not be stripped. We now always strip it, and allow the cookie middleware to re-add any cookies that it deems should be there. 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 to use your own redirect middleware, rather than ours. If you do not require or expect redirects to be followed, one should simply disable redirects all together.

信息暴露

Guzzle 信息泄露漏洞

Guzzle是guzzlehttp个人开发者的一个 PHP HTTP 客户端，可以轻松发送 HTTP 请求并轻松与 Web 服务集成。 Guzzle 6.5.6及之前版本、7.0.0 到 7.4.3 版本中存在信息泄露漏洞，该漏洞源于Cookie请求的标头是敏感信息，在向服务器发出请求时，该服务器会重定向到另一个主机来响应，Cookie标头也会被转发。
