Prior to versions 1.13.13, 1.14.8, and 1.15.2, in Cilium clusters with IPsec enabled and traffic matching Layer 7 policies, IPsec-eligible traffic between a node's Envoy proxy and pods on other nodes is sent unencrypted and IPsec-eligible traffic between a node's DNS proxy and pods on other nodes is sent unencrypted. This issue has been resolved in Cilium 1.15.2, 1.14.8, and 1.13.13. 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-j89h-qrvr-xc36","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-2024-28249","score":0.00271,"percentile":0.19347,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j89h-qrvr-xc36","url":"https://osv.dev/vulnerability/GHSA-j89h-qrvr-xc36","summary":"Unencrypted traffic between nodes when using IPsec and L7 policies","modified":"2026-09-10T03:50:10.563954422Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":["<1.13.13"],"fixed":["1.13.13"]},{"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-2024-2656","url":"https://osv.dev/vulnerability/GO-2024-2656","summary":"Unencrypted traffic between nodes with IPsec in github.com/cilium/cilium","modified":"2026-02-04T03:34:27.842721Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":["<1.13.13",">=1.14.0 <1.14.8",">=1.15.0 <1.15.2"],"fixed":["1.13.13","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).
