{"cve":"CVE-2025-47282","nvd":{"published":"2025-05-19T18:15:30.827","modified":"2026-06-17T09:27:39.790","status":"Deferred","description":"Gardener External DNS Management is an environment to manage external DNS entries for a kubernetes cluster. A security vulnerability was discovered in Gardener's External DNS Management prior to version 0.23.6 that could allow a user with administrative privileges for a Gardener project or a user with administrative privileges for a shoot cluster, including administrative privileges for a single namespace of the shoot cluster, to obtain control over the seed cluster where the shoot cluster is managed. This CVE affects all Gardener installations no matter of the public cloud provider(s) used for the seed clusters/shoot clusters. The affected component is `gardener/external-dns-management`. The `external-dns-management` component may also be deployed on the seeds by the `gardener/gardener-extension-shoot-dns-service` extension when the extension is enabled. In this case, all versions of the `shoot-dns-service` extension `<= v1.60.0` are affected by this vulnerability. Version 0.23.6 of Gardener External DNS Management fixes the issue.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-20"],"references":["https://github.com/gardener/external-dns-management/security/advisories/GHSA-xwgg-m7fx-83wx"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:01:57.636215869+00:00"},"epss":{"cve":"CVE-2025-47282","score":0.00743,"percentile":0.54732,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xwgg-m7fx-83wx","url":"https://osv.dev/vulnerability/GHSA-xwgg-m7fx-83wx","summary":"Gardener External DNS Management allows malicious google credential in DNS secret to lead to privilege escalation","modified":"2025-05-23T16:13:17.817202Z","packages":[{"ecosystem":"Go","name":"github.com/gardener/external-dns-management","purl":"pkg:golang/github.com/gardener/external-dns-management","ranges":["<0.23.6"],"fixed":["0.23.6"]},{"ecosystem":"Go","name":"github.com/gardener/gardener-extension-shoot-dns-service","purl":"pkg:golang/github.com/gardener/gardener-extension-shoot-dns-service","ranges":["<=1.6.0"],"fixed":[]}]},{"id":"GO-2025-3697","url":"https://osv.dev/vulnerability/GO-2025-3697","summary":"Gardener External DNS Management allows malicious google credential in DNS secret to lead to privilege escalation in github.com/gardener/external-dns-management","modified":"2026-03-03T04:56:35.933386Z","packages":[{"ecosystem":"Go","name":"github.com/gardener/external-dns-management","purl":"pkg:golang/github.com/gardener/external-dns-management","ranges":["<0.23.6"],"fixed":["0.23.6"]},{"ecosystem":"Go","name":"github.com/gardener/gardener-extension-shoot-dns-service","purl":"pkg:golang/github.com/gardener/gardener-extension-shoot-dns-service","ranges":["all versions"],"fixed":[]}]}],"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).
