From 1.9.4 until 1.14.5, a network DNS client allowed to request AXFR for a CoreDNS zone can trigger a panic when CoreDNS is configured with k8s_external headless-service zone transfers and Kubernetes contains a headless service endpoint with no declared ports; plugin/kubernetes/object/endpoint.go creates Port: -1, plugin/k8s_external/msg_to_dns.go skips that service, plugin/k8s_external/transfer.go sends an empty []dns.RR batch, and plugin/transfer/transfer.go indexes records[0] without checking the batch is non-empty. This issue is fixed in version 1.14.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","score":3.7},"cwes":["CWE-248","CWE-755"],"references":["https://github.com/coredns/coredns/commit/ab318db7b4a3a19273852ed627f54888198c8efb","https://github.com/coredns/coredns/pull/8207","https://github.com/coredns/coredns/releases/tag/v1.14.5","https://github.com/coredns/coredns/security/advisories/GHSA-74w3-63xv-x9mv","https://github.com/coredns/coredns/security/advisories/GHSA-74w3-63xv-x9mv"],"products":["coredns.io:coredns"],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-62994","score":0.00459,"percentile":0.39831,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-74w3-63xv-x9mv","url":"https://osv.dev/vulnerability/GHSA-74w3-63xv-x9mv","summary":"CoreDNS `k8s_external` headless AXFR can emit an empty transfer batch that panics the `transfer` plugin","modified":"2026-10-19T21:40:45.304482699Z","packages":[{"ecosystem":"Go","name":"github.com/coredns/coredns","purl":"pkg:golang/github.com/coredns/coredns","ranges":[">=1.9.4 <1.14.5"],"fixed":["1.14.5"]}]},{"id":"GO-2026-6805","url":"https://osv.dev/vulnerability/GO-2026-6805","summary":"CoreDNS `k8s_external` headless AXFR can emit an empty transfer batch that panics the `transfer` plugin in github.com/coredns/coredns","modified":"2026-10-19T21:31:38.407421025Z","packages":[{"ecosystem":"Go","name":"github.com/coredns/coredns","purl":"pkg:golang/github.com/coredns/coredns","ranges":[">=1.9.4 <1.14.5"],"fixed":["1.14.5"]}]}],"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).
