CVE-2022-29248
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 a PHP HTTP client. Guzzle prior to versions 6.5.6 and 7.4.3 contains a vulnerability with the cookie middleware. The vulnerability is that it is not checked if the cookie domain equals the domain of the server which sets the cookie via the Set-Cookie header, allowing a malicious server to set cookies for unrelated domains. The cookie middleware is disabled by default, so most library consumers will not be affected by this issue. Only those who manually add the cookie middleware to the handler stack or construct the client with ['cookies' => true] are affected. Moreover, those who do not use the same Guzzle client to call multiple domains and have disabled redirect forwarding are not affected by this vulnerability. Guzzle versions 6.5.6 and 7.4.3 contain a patch for this issue. As a workaround, turn off the cookie middleware.
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.

- 1. Identify which Guzzle version is in use by checking your project's composer.json or vendor/composer/installed.json
- 2. For Guzzle 6.x users: Run `composer require guzzlehttp/guzzle:^6.5.6` to upgrade to the fixed version
- 3. For Guzzle 7.x users: Run `composer require guzzlehttp/guzzle:^7.4.3` to upgrade to the fixed version
- 4. Run `composer update guzzlehttp/guzzle` to apply the changes
- 5. Verify the new version is installed: `composer show guzzlehttp/guzzle | grep version`
- 6. Test that your application's HTTP client functionality works correctly after the upgrade
- 7. For Drupal users: Ensure Drupal core or contributed modules are updated to versions 9.2.20+ or 9.314+ which include the patched Guzzle dependency
