There is no fixed version for Echo:latest guzzle.

NVD Description

Note: Versions mentioned in the description apply only to the upstream guzzle package and not the guzzle package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Guzzle is an extensible PHP HTTP client. Prior to 7.12.3, CookieJar did not restrict cookies scoped to IP-address or bare-numeric Domain values to the exact host that set them, because SetCookie::matchesDomain() applied ordinary suffix matching to domains such as 192.168.0.1, [::1], or 1, allowing cross-host cookie disclosure, cookie injection, or session fixation. This issue is fixed in version 7.12.3.
