{"cve":"CVE-2025-30162","nvd":{"published":"2025-03-24T19:15:52.767","modified":"2026-06-17T09:08:16.510","status":"Analyzed","description":"Cilium is a networking, observability, and security solution with an eBPF-based dataplane. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","score":4.3},"cwes":["CWE-863"],"references":["https://docs.cilium.io/en/stable/network/lb-ipam","https://github.com/cilium/cilium/security/advisories/GHSA-24qp-4xx8-3jvj","https://github.com/cilium/proxy/pull/1172"],"products":["cilium:cilium"],"source":"nvd","synced_at":"2026-10-19T22:00:28.034033815+00:00"},"epss":{"cve":"CVE-2025-30162","score":0.00224,"percentile":0.13062,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-24qp-4xx8-3jvj","url":"https://osv.dev/vulnerability/GHSA-24qp-4xx8-3jvj","summary":"Cilium East-west traffic not subject to egress policy enforcement for requests via Gateway API load balancers","modified":"2026-09-10T03:50:06.165871995Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.16.0 <1.16.8"],"fixed":["1.16.8"]},{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.17.0 <1.17.2"],"fixed":["1.17.2"]},{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.15.0 <1.15.15"],"fixed":["1.15.15"]}]},{"id":"GO-2025-3560","url":"https://osv.dev/vulnerability/GO-2025-3560","summary":"Cilium East-west traffic not subject to egress policy enforcement for requests via Gateway API load balancers in github.com/cilium/cilium","modified":"2026-02-04T04:35:35.741655Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.15.0 <1.15.15",">=1.16.0 <1.16.8",">=1.17.0 <1.17.2"],"fixed":["1.15.15","1.16.8","1.17.2"]}]}],"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).
