Release notes

v0.24.0

Changes

security: disable kubernetes external name by default, fixes CVE-2026-24470

ref: GHSA-mxxc-p822-2hx9

This release breaks end-users and library-users that depend on Kubernetes Ingress referencing a Kubernetes service type ExternalName.

If you are end-user and depend on the former behavior, you can pass -enable-kubernetes-external-names to your deployment. If you are library-user and depend on the former behavior, you can pass the following option to restore behavior:

skipper.Run(skipper.Options{
    EnableExternalNames: true,
})

Thanks https://github.com/b0b0haha and https://github.com/moyushui and https://github.com/j311yl0v3u providing us a detailed report how to exploit this vulnerability that is available by default in skipper versions <v0.24
