{"cve":"CVE-2025-30163","nvd":{"published":"2025-03-24T19:15:52.937","modified":"2026-06-17T09:08:16.627","status":"Analyzed","description":"Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Node based network policies (`fromNodes` and `toNodes`) will incorrectly permit traffic to/from non-node endpoints that share the labels specified in `fromNodes` and `toNodes` sections of network policies. Node based network policy is disabled by default in Cilium. This issue affects: Cilium 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 v1.16.8 and v1.17.2. Users can work around this issue by ensuring that the labels used in `fromNodes` and `toNodes` fields are used exclusively by nodes and not by other endpoints.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","score":4.7},"cwes":["CWE-863"],"references":["https://docs.cilium.io/en/stable/security/policy/language/#node-based","https://github.com/cilium/cilium/pull/36657","https://github.com/cilium/cilium/security/advisories/GHSA-c6pf-2v8j-96mc"],"products":["cilium:cilium"],"source":"nvd","synced_at":"2026-10-19T22:00:28.034033815+00:00"},"epss":{"cve":"CVE-2025-30163","score":0.0021,"percentile":0.11158,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-c6pf-2v8j-96mc","url":"https://osv.dev/vulnerability/GHSA-c6pf-2v8j-96mc","summary":"Cilium node based network policies may incorrectly allow workload traffic","modified":"2026-07-02T20:30:11.439175006Z","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"]}]},{"id":"GO-2025-3561","url":"https://osv.dev/vulnerability/GO-2025-3561","summary":"Cilium node based network policies may incorrectly allow workload traffic in github.com/cilium/cilium","modified":"2026-03-03T04:57:14.588260Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.16.0 <1.16.8",">=1.17.0 <1.17.2"],"fixed":["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).
