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

high Tenable Self-Hosted Container Security Plugin ID 458141

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 1.16.4,
kyverno’s apiCall servicecall helper implicitly injects Authorization: Bearer ... using the kyverno
controller serviceaccount token when a policy does not explicitly set an Authorization header. Because
context.apiCall.service.url is policy-controlled, this can send the kyverno serviceaccount token to an
attacker-controlled endpoint (confused deputy). Namespaced policies are blocked from servicecall usage by
the namespaced urlPath gate in pkg/engine/apicall/apiCall.go, so this report is scoped to ClusterPolicy
and global context usage. This vulnerability is fixed in 1.16.4. (CVE-2026-40868)

Solution

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