NVD Description

Note: Versions mentioned in the description apply only to the upstream privatebin package and not the privatebin 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.
