Summary
Duplicate Advisory: Guzzle: Host-only cookie scope is not preserved
Advisory details
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-wm3w-8rrp-j577. This link is maintained to preserve external references.
Original Description
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.
