How to fix?

There is no fixed version for Echo:latest golang-1.19.

NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-1.19 package and not the golang-1.19 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Matching of hosts against proxy patterns can improperly treat an IPv6 zone ID as a hostname component. For example, when the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be proxied.
