SCA: security update for github.com/kubewarden/kubewarden-controller (GHSA-6r7f-3fwq-hq74)

medium Tenable Cloud Security Plugin ID 438501

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Kubewarden is a policy engine for Kubernetes. Kubewarden cluster operators can grant permissions to users
 to deploy namespaced AdmissionPolicies and AdmissionPolicyGroups in their Namespaces. One of Kubewarden
 promises is that configured users can deploy namespaced policies in a safe manner, without privilege
 escalation. An attacker with privileged "AdmissionPolicy" create permissions (which isn't the default)
 could make use of 3 deprecated host-callback APIs: kubernetes/ingresses, kubernetes/namespaces,
 kubernetes/services. The attacker can craft a policy that exercises these deprecated API calls and would
 allow them read access to Ingresses, Namespaces, and Services resources respectively. This attack is read-
 only, there is no write capability and no access to Secrets, ConfigMaps, or other resource types beyond
 these three. (CVE-2026-29773)

Solution

Update the github.com/kubewarden/kubewarden-controller library and its related packages to version 1.33.0 or later.
