SCA: security update for github.com/cilium/cilium (GHSA-h78m-j95m-5356)

medium Tenable Self-Hosted Container Security Plugin ID 415560

Description

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

 - Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An insecure
 default `Access-Control-Allow-Origin` header value could lead to sensitive data exposure for users of
 Cilium versions 1.14.0 through 1.14.7, 1.15.0 through 1.15.11, and 1.16.0 through 1.16.4 who deploy Hubble
 UI using either Cilium CLI or via the Cilium Helm chart. A user with access to a Hubble UI instance
 affected by this issue could leak configuration details about the Kubernetes cluster which Hubble UI is
 monitoring, including node names, IP addresses, and other metadata about workloads and the cluster
 networking configuration. In order for this vulnerability to be exploited, a victim would have to first
 visit a malicious page. This issue is fixed in Cilium v1.14.18, v1.15.12, and v1.16.5. As a workaround,
 users who deploy Hubble UI using the Cilium Helm chart directly can remove the CORS headers from the Helm
 template as shown in the patch from commit a3489f190ba6e87b5336ee685fb6c80b1270d06d. (CVE-2025-23047)
