Prior to version 2.8.0, Kube-router's proxy module does not validate externalIPs or loadBalancer IPs before programming them into the node's network configuration. Version 2.8.0 contains a patch for the issue. Available workarounds include enabling DenyServiceExternalIPs feature gate, deploying admission policy, restricting service creation RBAC, monitoring service changes, and applying BGP prefix filtering.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","score":7.1},"cwes":["CWE-284"],"references":["https://github.com/cloudnativelabs/kube-router/commit/a1f0b2eea3ee0f66b9a5b5c49dcb714619ccd456","https://github.com/cloudnativelabs/kube-router/releases/tag/v2.8.0","https://github.com/cloudnativelabs/kube-router/security/advisories/GHSA-phqm-jgc3-qf8g","https://github.com/cloudnativelabs/kube-router/security/advisories/GHSA-phqm-jgc3-qf8g"],"products":["kube-router:kube-router"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-32254","score":0.00309,"percentile":0.23768,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-phqm-jgc3-qf8g","url":"https://osv.dev/vulnerability/GHSA-phqm-jgc3-qf8g","summary":"Kube-router Proxy Module Blindly Trusts ExternalIPs/LoadBalancer IPs Enabling Cluster-Wide Traffic Hijacking and DNS DoS","modified":"2026-03-30T14:01:29Z","packages":[{"ecosystem":"Go","name":"github.com/cloudnativelabs/kube-router/v2","purl":"pkg:golang/github.com/cloudnativelabs/kube-router/v2","ranges":["<2.8.0"],"fixed":["2.8.0"]}]},{"id":"GO-2026-4724","url":"https://osv.dev/vulnerability/GO-2026-4724","summary":"Kube-router Proxy Module Blindly Trusts ExternalIPs/LoadBalancer IPs Enabling Cluster-Wide Traffic Hijacking and DNS DoS in github.com/cloudnativelabs/kube-router","modified":"2026-03-26T21:03:15.216034Z","packages":[{"ecosystem":"Go","name":"github.com/cloudnativelabs/kube-router","purl":"pkg:golang/github.com/cloudnativelabs/kube-router","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/cloudnativelabs/kube-router/v2","purl":"pkg:golang/github.com/cloudnativelabs/kube-router/v2","ranges":["<2.8.0"],"fixed":["2.8.0"]}]}],"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).
