CVE-2022-31043— Guzzle 信息泄露漏洞

Fix failure to strip Authorization header on HTTP downgrade in Guzzle

Guzzle is an open source PHP HTTP client. In affected versions `Authorization` 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, we should not forward the `Authorization` header on. This is much the same as to how we don't forward on the header if the host changes. Prior to this fix, `https` to `http` downgrades did not result in the `Authorization` header being removed, only changes to the host. 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 which would be to use their own redirect middleware. Alternately users may simply disable redirects all together if redirects are not expected or required.

信息暴露

Guzzle 信息泄露漏洞

PHP是一种在服务器端执行的脚本语言。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，Authorization标头也会被转发。
