Echo: github.com/kyverno/kyverno: security update to 1.17.0

critical Tenable Cloud Security Plugin ID 461650

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
 1.18.0-rc1, 1.17.2-rc1, and 1.16.4, Kyverno's apiCall feature in ClusterPolicy automatically attaches the
 admission controller's ServiceAccount token to outgoing HTTP requests. The service URL has no validation —
 it can point anywhere, including attacker-controlled servers. Since the admission controller SA has
 permissions to patch webhook configurations, a stolen token leads to full cluster compromise. Versions
 1.18.0-rc1, 1.17.2-rc1, and 1.16.4 patch the issue. (CVE-2026-41323)

Solution

Update the github.com/kyverno/kyverno library and its related packages to version 1.17.0 or later.
