Vulnerability details
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.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
The control's identification, isolation, alerting, and eradication steps directly limit the impact and exploitation window of unauthorized sensitive information exposure.
Proper media downgrading process prevents sensitive information from remaining on media that is then accessible to lower-classification recipients.
Policies requiring periodic review and deletion of inaccurate/outdated PII reduce the amount of sensitive information retained and therefore exposed.
Regular deletion of inaccurate or outdated PII directly reduces the volume of sensitive information retained that could be exposed.
De-identification directly prevents exposure of sensitive/PII data to unauthorized actors when datasets are released or shared.
Deleting information when no longer needed directly reduces the window during which sensitive data can be exposed to unauthorized actors.
Secure disposal techniques directly prevent sensitive data from becoming accessible to unauthorized actors after components leave organizational control.
Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.
