Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Starting in version 1.14.0 and prior to versions 1.14.8 and 1.15.2, In Cilium clusters with WireGuard enabled and traffic matching Layer 7 policies Wireguard-eligible traffic that is sent between a node's Envoy proxy and pods on other nodes is sent unencrypted and Wireguard-eligible traffic that is sent between a node's DNS proxy and pods on other nodes is sent unencrypted. This issue has been resolved in Cilium 1.14.8 and 1.15.2 in in native routing mode (`routingMode=native`) and in Cilium 1.14.4 in tunneling mode (`routingMode=tunnel`). Not that in tunneling mode, `encryption.wireguard.encapsulate` must be set to `true`. There is no known workaround for this issue.

GHSA-v6q2-4qr3-5cw6Unencrypted traffic between nodes when using WireGuard and L7 policies2024-03-18ghsa · osvUS
### Impact In Cilium clusters with WireGuard enabled and traffic matching Layer 7 policies: - Traffic that should be WireGuard-encrypted is sent unencrypted between a node's Envoy proxy and pods on other nodes. - Traffic that should be WireGuard-encrypted is sent unencrypted between a node's DNS proxy and pods on other nodes. ### Patches This issue affects: * In native routing mode (`routingMode=native`): * Cilium v1.14 versions before v1.14.8 * Cilium v1.15 versions before v1.15.2 * In tunneling mode (`routingMode=tunnel`): * Cilium v1.14 versions before v1.14.4 * Cilium v1.14.4 if `encryption.wireguard.encapsulate` is set to `false` (default). This issue has been resolved in: * In native routing mode (`routingMode=native`): * Cilium v1.14.8 * Cilium v1.15.2 * In tunneling mode (`routingMode=tunnel`): * Cilium v1.14.4. **NOTE** `encryption.wireguard.encapsulate` must be set to `true`. ### Workarounds There is no workaround to this issue. ### Acknowledgements The Cilium community has worked together with members of Isovalent to prepare these mitigations. Special thanks to @brb, @giorio94, @gandro and @jschwinger233 for their work on triaging and remediating this issue. ### For more information If you have any questions or comments about this advisory, please reach out on [Slack](https://docs.cilium.io/en/latest/community/community/#slack). If you think you found a related vulnerability, we strongly encourage you to report security vulnerabilities to our private security mailing list at [security@cilium.io](mailto:security@cilium.io). This is a private mailing list where only members of the Cilium internal security team are subscribed to, and your report will be treated as top priority.
