Note: Versions mentioned in the description apply only to the upstream loki-3.4 package and not the loki-3.4 package as distributed by Chainguard. See How to fix? for Chainguard 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.
