CVE-2022-31043
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedGuzzle 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisThe application discloses data — error detail, internal paths, tokens, or other users' records — to someone who shouldn't see it. On its own it can look minor, but it hands attackers the map they need for a larger attack. Remediation is about minimising what's returned and enforcing authorization on every piece of data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped6.5.77.4.49.2.21
Guzzle 7.4.4 (for Guzzle 7.x) or Guzzle 6.5.7 (for Guzzle 6.x); Drupal 9.2.21+, 9.3.16+, or 9.4.1+
- Identify the Guzzle version currently used in your project (check composer.json or composer.lock)
- If using Guzzle 7.x: Run `composer require guzzlehttp/guzzle:^7.4.4` to upgrade to version 7.4.4
- If using Guzzle 6.x: Run `composer require guzzlehttp/guzzle:^6.5.7` to upgrade to version 6.5.7
- Run `composer update guzzlehttp/guzzle` to install the updated package
- Verify the installed version with `composer show guzzlehttp/guzzle`
- Test your application's HTTP request functionality to ensure the upgrade does not break existing functionality
- For Drupal users: Update Drupal core or modules that depend on Guzzle to versions that include the fixed Guzzle release (Drupal 9.2.21+, 9.3.16+, or 9.4.1+)
