{"id":"CVE-2025-30162","state":"PUBLISHED","title":"East-west traffic not subject to egress policy enforcement for requests via Gateway API load balancers","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.","publishedAt":"2025-03-24T18:44:07.927Z","updatedAt":"2025-03-24T19:30:18.385Z","severity":{"score":3.2,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["cilium cilium"],"affected":[{"vendor":"cilium","product":"cilium","versions":[{"version":">= 1.16.0, < 1.16.8","status":"affected"},{"version":">= 1.17.0, < 1.17.2","status":"affected"},{"version":">= 1.15.0, < 1.15.15","status":"affected"}]}],"references":["https://github.com/cilium/cilium/security/advisories/GHSA-24qp-4xx8-3jvj","https://github.com/cilium/proxy/pull/1172","https://docs.cilium.io/en/stable/network/lb-ipam"],"weaknesses":["CWE-863"],"ingestedAt":"2026-10-29T20:08:55.257Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/30xxx/CVE-2025-30162.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-30162","state":"PUBLISHED","datePublished":"2025-03-24T18:44:07.927Z","dateUpdated":"2025-03-24T19:30:18.385Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-03-17T12:41:42.567Z"},"containers":{"cna":{"title":"East-west traffic not subject to egress policy enforcement for requests via Gateway API load balancers","descriptions":[{"lang":"en","value":"Cilium is a networking, observability, and security solution with an eBPF-based dataplane.
