This can lead to arbitrary code execution in the context of the ingress-nginx controller, and disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)","published":"2025-03-24T23:29:15.610Z","modified":"2026-08-12T03:51:46.854865195Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.83498,"percentile":0.99658,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"Go","name":"k8s.io/ingress-nginx","fixedVersion":"1.11.5"},{"ecosystem":"Go","name":"k8s.io/ingress-nginx","fixedVersion":"1.12.1"}],"fix":null,"references":[{"type":"WEB","url":"https://www.exploit-db.com/exploits/52475"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/1xxx/CVE-2025-1098.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-1098"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20250328-0008/"},{"type":"REPORT","url":"https://github.com/kubernetes/kubernetes/issues/131008"},{"type":"PACKAGE","url":"https://github.com/kubernetes/ingress-nginx"},{"type":"WEB","url":"https://github.com/kubernetes/ingress-nginx/releases/tag/controller-v1.11.5"},{"type":"WEB","url":"https://github.com/kubernetes/ingress-nginx/releases/tag/controller-v1.12.1"},{"type":"WEB","url":"https://groups.google.com/g/kubernetes-security-announce/c/2qa9DFtN0cQ"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20250328-0008"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:46.854865195Z"}}
