How to fix?

Upgrade Chainguard cert-manager-1.16 to version 1.16.4-r5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cert-manager-1.16 package and not the cert-manager-1.16 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.
