NVD Description

Note: Versions mentioned in the description apply only to the upstream drupal-11.3 package and not the drupal-11.3 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

guzzlehttp/guzzle versions before 7.15.1 fail to preserve host-only cookie scope, storing the request host in the Domain field instead of marking cookies as host-only. Attackers controlling child hosts can receive host-only cookies intended only for parent hosts, potentially disclosing session identifiers and authorization tokens when the same cookie jar is reused across trust boundaries.
