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.","affected":[{"package":{"name":"cilium","ecosystem":"Bitnami","purl":"pkg:bitnami/cilium"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.15.0"},{"fixed":"1.17.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/cilium/BIT-cilium-2025-30162.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N"}]}],"references":[{"type":"WEB","url":"https://docs.cilium.io/en/stable/network/lb-ipam"},{"type":"ADVISORY","url":"https://github.com/cilium/cilium/security/advisories/GHSA-24qp-4xx8-3jvj"},{"type":"FIX","url":"https://github.com/cilium/proxy/pull/1172"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-30162"}],"database_specific":{"cpes":["cpe:2.3:a:cilium:cilium:*:*:*:*:*:go:*:*"],"severity":"Medium"}}
