When a stored cookie's `Domain` attribute is an IPv4 literal (`Domain=192.168.0.1`), a bracketed IPv6 literal (`Domain=[::1]`), or a bare numeric value that denotes an IPv4 address (`Domain=1`, which is `0.0.0.1`), `SetCookie::matchesDomain()` applies ordinary subdomain (suffix) matching to it instead of requiring an exact host. The IP-address check inside `matchesDomain()` is applied only to the request host and never to the cookie's own domain, and response cookies that carry an explicit `Domain` attribute are stored as suffix-matchable. As a result Guzzle sends such a cookie to any host whose name ends in that value as a trailing label, for example sending a `Domain=192.168.0.1` cookie to `evil.192.168.0.1`, or a `Domain=1` cookie to `evil.1`. The same flaw lets a look-alike host store a cookie that Guzzle then sends to the bare IP address. Depending on how the receiving service interprets the cookie, the impact is cross-host cookie disclosure, cookie injection, or session fixation.\n\nYou are affected if your application uses Guzzle's cookie support, for example `new Client([","public_affected_ranges":["ECOSYSTEM: introduced 0; fixed 7.12.3"]}],"null_published_at":"2026-10-31T22:13:01.450Z","source_updated_at":"2026-09-10T03:50:51.915Z","source_disclosed_at":"2026-07-20T22:00:09.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:42:20.411Z"}],"next_cursor":null,"snapshot_revision":"42594"}
