Vulnerability Title
guzzlehttp/guzzle before 7.15.1 Host-only Cookie Scope
Source: CVE Program / CVE List V5
Vulnerability 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.
