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access all Secrets cluster-wide.)","modified":"2026-05-20T08:11:53.551698484Z","published":"2026-02-10T08:50:33.151Z","withdrawn":"2026-05-20T08:00:05.758306172Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:kubernetes:ingress-nginx:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://github.com/kubernetes/kubernetes/issues/136789"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-15566"}],"affected":[{"package":{"name":"nginx-ingress-controller","ecosystem":"Bitnami","purl":"pkg:bitnami/nginx-ingress-controller"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.13.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/nginx-ingress-controller/BIT-nginx-ingress-controller-2025-15566.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"}
