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.","published":"2024-03-18T21:36:10.510Z","modified":"2026-08-12T03:51:36.395504763Z","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":"1.13.13"},{"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-2024-28249.json"},{"type":"ADVISORY","url":"https://github.com/cilium/cilium/security/advisories/GHSA-j89h-qrvr-xc36"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-28249"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:36.395504763Z"}}
