CVE-2026-67355

guzzlehttp/guzzle before 7.15.1 Host-only Cookie Scope PUBLISHED

Description (CNA)

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.
