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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N","score":6.1},"cwes":["CWE-319","CWE-311"],"references":["https://github.com/cilium/cilium/releases/tag/v1.13.13","https://github.com/cilium/cilium/releases/tag/v1.14.8","https://github.com/cilium/cilium/releases/tag/v1.15.2","https://github.com/cilium/cilium/security/advisories/GHSA-v6q2-4qr3-5cw6","https://github.com/cilium/cilium/releases/tag/v1.13.13"],"products":["cilium:cilium"],"source":"nvd","synced_at":"2026-10-19T21:46:54.846886191+00:00"},"epss":{"cve":"CVE-2024-28250","score":0.00172,"percentile":0.06518,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-v6q2-4qr3-5cw6","url":"https://osv.dev/vulnerability/GHSA-v6q2-4qr3-5cw6","summary":"Unencrypted traffic between nodes when using WireGuard and L7 policies","modified":"2026-09-10T03:50:10.846938875Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.14.0 <1.14.8"],"fixed":["1.14.8"]},{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.15.0 <1.15.2"],"fixed":["1.15.2"]}]},{"id":"GO-2024-2657","url":"https://osv.dev/vulnerability/GO-2024-2657","summary":"Unencrypted traffic between nodes with WireGuard in github.com/cilium/cilium","modified":"2026-02-04T04:36:29.585552Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.14.0 <1.14.8",">=1.15.0 <1.15.2"],"fixed":["1.14.8","1.15.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
