Echo: github.com/kyverno/kyverno: security update to 1.16.4

high Tenable Self-Hosted Container Security Plugin ID 458367

Description

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

 - Kyverno is a policy engine designed for cloud native platform engineering teams. Prior to versions 1.17.2
 and 1.16.4, an unchecked type assertion in the `forEach` mutation handler allows any user with permission
 to create a `Policy` or `ClusterPolicy` to crash the cluster-wide background controller into a persistent
 CrashLoopBackOff. The same bug also causes the admission controller to drop connections and block all
 matching resource operations. The crash loop persists until the policy is deleted. The vulnerability is
 confined to the legacy engine, and CEL-based policies are unaffected. Versions 1.17.2 and 1.16.4 fix the
 issue. (CVE-2026-41485)

Solution

Update the github.com/kyverno/kyverno library and its related packages to version 1.16.4 or later.
