For Cilium users who use Gateway API for Ingress for some services and use LB-IPAM or BGP for LB Service implementation and use network policies to block egress traffic from workloads in a namespace to workloads in other namespaces, egress traffic from workloads covered by such network policies to LoadBalancers configured by `Gateway` resources will incorrectly be allowed. LoadBalancer resources not deployed via a Gateway API configuration are not affected by this issue. This issue affects: Cilium v1.15 between v1.15.0 and v1.15.14 inclusive, v1.16 between v1.16.0 and v1.16.7 inclusive, and v1.17 between v1.17.0 and v1.17.1 inclusive. This issue is fixed in Cilium v1.15.15, v1.16.8, and v1.17.2. A Clusterwide Cilium Network Policy can be used to work around this issue for users who are unable to upgrade.","published":"2025-03-24T18:44:07.927Z","modified":"2026-08-08T03:48:12.523144131Z","cvss":{"score":3.2,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","fixedVersion":"1.16.8"},{"ecosystem":"Go","name":"github.com/cilium/cilium","fixedVersion":"1.17.2"},{"ecosystem":"Go","name":"github.com/cilium/cilium","fixedVersion":"1.15.15"}],"fix":{"url":"https://github.com/cilium/proxy/pull/1172","label":"cilium/proxy#1172"},"references":[{"type":"WEB","url":"https://docs.cilium.io/en/stable/network/lb-ipam"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/30xxx/CVE-2025-30162.json"},{"type":"ADVISORY","url":"https://github.com/cilium/cilium/security/advisories/GHSA-24qp-4xx8-3jvj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-30162"},{"type":"FIX","url":"https://github.com/cilium/proxy/pull/1172"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:48:12.523144131Z"}}
