How to fix?

Upgrade github.com/cilium/cilium to version 1.14.7 or higher.

Overview

github.com/cilium/cilium is an open source software for providing and transparently securing network connectivity and loadbalancing between application workloads such as application containers or processes.

Affected versions of this package are vulnerable to Cleartext Transmission of Sensitive Information due to the handling of ingress/health traffic when using Wireguard transparent encryption. An attacker can intercept and read responses from pods to the Ingress and health endpoints, which are not encrypted under certain configurations.

Note:

This vulnerability does not affect traffic from the Ingress and health endpoints to pods. The health endpoint is specifically used for Cilium's internal health checks.
