Unencrypted traffic between pods when using Wireguard and an external kvstore

### Impact For Cilium users who have enabled [an external kvstore](https://docs.cilium.io/en/stable/installation/k8s-install-external-etcd/#when-do-i-need-to-use-a-kvstore) and [Wireguard transparent encryption](https://docs.cilium.io/en/stable/security/network/encryption-wireguard/#encryption-wg), traffic between pods in the affected cluster is not encrypted. ### Patches This issue affects Cilium v1.14 before v1.14.7. This issue has been patched in Cilium v1.14.7. ### Workarounds There is no workaround to this issue - affected users are encouraged to upgrade. ### Acknowledgements The Cilium community has worked together with members of Isovalent to prepare these mitigations.
