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.","published":"2024-03-18T21:42:21.689Z","modified":"2026-08-08T03:48:02.823801210Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","fixedVersion":"1.14.8"},{"ecosystem":"Go","name":"github.com/cilium/cilium","fixedVersion":"1.15.2"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/cilium/cilium/releases/tag/v1.13.13"},{"type":"WEB","url":"https://github.com/cilium/cilium/releases/tag/v1.14.8"},{"type":"WEB","url":"https://github.com/cilium/cilium/releases/tag/v1.15.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/28xxx/CVE-2024-28250.json"},{"type":"ADVISORY","url":"https://github.com/cilium/cilium/security/advisories/GHSA-v6q2-4qr3-5cw6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-28250"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:48:02.823801210Z"}}
