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access all Secrets cluster-wide.)","modified":"2026-05-20T08:11:53.553361089Z","published":"2025-03-26T07:25:07.352Z","withdrawn":"2026-05-20T08:00:05.763200852Z","database_specific":{"cpes":["cpe:2.3:a:kubernetes:ingress-nginx:*:*:*:*:*:*:*:*","cpe:2.3:a:kubernetes:ingress-nginx:*:*:*:*:*:go:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://github.com/kubernetes/kubernetes/issues/131007"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-1097"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20250328-0008/"},{"type":"WEB","url":"https://www.exploit-db.com/exploits/52475"}],"affected":[{"package":{"name":"nginx-ingress-controller","ecosystem":"Bitnami","purl":"pkg:bitnami/nginx-ingress-controller"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.11.7"},{"introduced":"1.12.0"},{"fixed":"1.12.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/nginx-ingress-controller/BIT-nginx-ingress-controller-2025-1097.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.7.3"}
