SCA: security update for github.com/kyverno/kyverno (GHSA-q93q-v844-jrqp)

high Tenable Self-Hosted Container Security Plugin ID 440364

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.
