Kubewarden 1.5.0 release

Author: José Guilherme Vanz



Today we’re pleased to announce the availability of Kubewarden 1.5.0!

This release brings the usual amount of small bug fixes, dependency updates, and a major security enhancement. Let’s take a closer look!

Policy evaluation timeout

The Kubewarden team is constantly working to improve the security posture of the project. As part of these efforts, we’re excited to introduce the new “policy evaluation timeout” feature.

Starting from this release, Policy Server will interrupt the evaluation of admission requests after a certain amount of time has elapsed. This security feature, which is enabled by default, prevents a Policy Server from running out of computing resources because one or more of its policy evaluations are stuck in infinite loops. This mitigates a type of Denial Of Service (DOS) attacks against the Policy Server.

Take a look at the Kubewarden documentation to get more information about this new feature.

Changes to kwctl

kwctl now imports the trusted certificate authorities from the host system. Thus, kwctl interactions with registries secured by certificates issued by 3rd party certificate authorities becomes simpler.

Note, it’s still possible to fine tune the certificates to be used via the sources.yml file.

Changes to Kubewarden controller

The validation of ClusterAdmissionPolicy and AdmissionPolicy custom resources has been extended. The new validation checks are able to prevent the creation of resources that do not have any rule specified.

We would like to thank our wonderful community for this contribution.


Furthermore, the changelog of the main Kubewarden components (policy-server, kubewarden-controller and kwctl) are now being generated using the release-drafter project.

Starting from this release, the Changelog file is no longer available inside of the root of these git projects, rather it has been made available under the release section of the individual repositories.

Go, grab it!

We are eager to know what you think about Kubewarden and this release.
