Moderately Critical Drupal Core Security Update

Staff Reporter

Drupal uses the third-party, Guzzle library for handling HTTP requests and responses to external services. Guzzle has released two security advisories:

Failure to strip the Cookie header on change in host or HTTP downgrade
Fix failure to strip Authorization header on HTTP downgrade

These do not affect Drupal core, but may affect some contributed projects or custom code on Drupal sites.

The Drupal security team is issuing this security advisory outside their regular Drupal security release window schedule since Guzzle has already published information about the vulnerabilities, and vulnerabilities might exist in contributed modules or custom modules that use Guzzle for outgoing requests. Guzzle has rated these vulnerabilities as high-risk.

This advisory is not covered by Drupal Steward.

Solution:
Install the latest version:

If you are using Drupal 9.4, update to Drupal 9.4.0-rc2.
If you are using Drupal 9.3, update to Drupal 9.3.16.
If you are using Drupal 9.2, update to Drupal 9.2.21.

All versions of Drupal 9 prior to 9.2.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Drupal 7 is not affected.

Advanced users may also work around this issue by temporarily using drupal/core instead of drupal/core-recommended and then updating Guzzle to the desired version. More information on managing Guzzle with Drupal 9.4.
