{"id":"CVE-2025-15566","summary":"ingress-nginx auth-proxy-set-headers nginx configuration injection","details":"A security issue was discovered in ingress-nginx where the `nginx.ingress.kubernetes.io/auth-proxy-set-headers` Ingress annotation can be used to inject configuration into nginx. 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":"2026-07-15T01:49:22.210776443Z","published":"2026-02-06T03:13:51.717Z","database_specific":{"cna_assigner":"kubernetes","cwe_ids":["CWE-20"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/15xxx/CVE-2025-15566.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/15xxx/CVE-2025-15566.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-15566"},{"type":"REPORT","url":"https://github.com/kubernetes/kubernetes/issues/136789"},{"type":"PACKAGE","url":"https://github.com/kubernetes/ingress-nginx"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kubernetes/ingress-nginx","events":[{"introduced":"0"},{"fixed":"dcc3288f7c1755b9cfb5eedf97107e5a0f185d3b"},{"fixed":"3bb5d0c12e6146dac70cc0c4d70740cf2f1d010e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.12.5"},{"fixed":"1.13.1"}],"source":"AFFECTED_FIELD"}}],"versions":["helm-chart-4.12.4","controller-v1.12.4","helm-chart-4.13.0","controller-v1.13.0","helm-chart-4.12.3","controller-v1.12.3","helm-chart-4.12.2","controller-v1.12.2","helm-chart-4.12.1","controller-v1.12.1","helm-chart-4.12.0","controller-v1.12.0","helm-chart-4.12.0-beta.0","controller-v1.12.0-beta.0","helm-chart-4.11.0","controller-v1.11.0","controller-v1.10.1","helm-chart-4.10.0","controller-v1.10.0","helm-chart-4.9.1","helm-chart-4.9.0","controller-v1.9.5","helm-chart-4.8.3","controller-v1.9.4","helm-chart-4.8.2","controller-v1.9.3","helm-chart-4.8.1","controller-v1.9.1","helm-chart-4.8.0","controller-v1.9.0-beta.0","helm-chart-4.8.0-beta.0","helm-chart-4.7.2","helm-chart-4.7.1","helm-chart-4.7.0","controller-v1.8.0","helm-chart-4.6.1","controller-v1.7.1","helm-chart-4.6.0","controller-v1.7.0","helm-chart-4.5.2","controller-v1.6.4","helm-chart-4.5.0","helm-chart-4.4.2","helm-chart-4.4.0","controller-v1.5.1","helm-chart-4.3.0","controller-v1.4.0","helm-chart-4.2.5","controller-v1.3.1","helm-chart-4.2.4","helm-chart-4.2.3","helm-chart-4.2.2","helm-chart-4.2.1","helm-chart-4.2.0","controller-v1.3.0","helm-chart-4.1.4","helm-chart-4.1.3","controller-v1.2.1","helm-chart-4.1.2","helm-chart-4.1.1","helm-chart-4.1.0","controller-v1.2.0","helm-chart-4.1.0-beta.1","controller-v1.2.0-beta.1","controller-v1.2.0-beta.0","helm-chart-4.1.0-beta.0","helm-chart-4.0.19","controller-v1.1.3","helm-chart-4.0.18","controller-v1.1.2","helm-chart-4.0.17","helm-chart-4.0.16","helm-chart-4.0.15","controller-v1.1.1","helm-chart-4.0.13","helm-chart-4.0.12","helm-chart-4.0.11","helm-chart-4.0.10","controller-v1.1.0","helm-chart-4.0.9","helm-chart-4.0.8","helm-chart-4.0.7","controller-v1.0.5","helm-chart-4.0.6","controller-v1.0.4","helm-chart-4.0.5","helm-chart-4.0.4","controller-v1.0.3","helm-chart-4.0.3","controller-v1.0.2","helm-chart-4.0.2","controller-v1.0.1","helm-chart-4.0.1","controller-v1.0.0","helm-chart-3.36.0","controller-v0.49.0","helm-chart-3.35.0","controller-v0.48.1","helm-chart-3.34.0","controller-v0.47.0","helm-chart-3.33.0","helm-chart-3.32.0","helm-chart-3.31.0","helm-chart-3.30.0","controller-v0.46.0","helm-chart-3.29.0","helm-chart-3.28.0","controller-v0.45.0","helm-chart-3.27.0","helm-chart-3.26.0","helm-chart-3.24.0","helm-chart-3.25.0","controller-v0.44.0","helm-chart-3.23.0","helm-chart-3.22.0","helm-chart-3.21.0","helm-chart-3.20.1","helm-chart-3.20.0","controller-v0.42.0","controller-v0.43.0","helm-chart-3.19.0","helm-chart-3.18.0","helm-chart-3.17.0","helm-chart-3.16.1","helm-chart-3.16.0","ingress-nginx-3.15.2","ingress-nginx-3.15.1","ingress-nginx-3.15.0","ingress-nginx-3.13.0","ingress-nginx-3.12.0","ingress-nginx-3.11.1","ingress-nginx-3.11.0","controller-v0.41.2","ingress-nginx-3.10.1","controller-v0.41.1","ingress-nginx-3.10.0","ingress-nginx-3.9.0","ingress-nginx-3.8.0","controller-v0.41.0","ingress-nginx-3.7.1","ingress-nginx-3.4.1","ingress-nginx-3.7.0","ingress-nginx-3.6.0","ingress-nginx-3.5.1","ingress-nginx-3.5.0","controller-v0.40.2","ingress-nginx-3.4.0","controller-v0.40.1","ingress-nginx-3.3.1","controller-v0.40.0","ingress-nginx-3.3.0","ingress-nginx-3.2.0","ingress-nginx-3.1.0","ingress-nginx-3.0.0","ingress-nginx-2.16.0","ingress-nginx-2.15.0","ingress-nginx-2.14.0","ingress-nginx-2.13.0","controller-v0.35.0","ingress-nginx-2.12.1","ingress-nginx-2.12.0","ingress-nginx-2.11.3","ingress-nginx-2.11.2","controller-v0.34.1","ingress-nginx-2.11.1","ingress-nginx-2.11.0","controller-v0.34.0","ingress-nginx-2.10.0","ingress-nginx-2.9.1","ingress-nginx-2.9.0","ingress-nginx-2.8.0","ingress-nginx-2.7.1","ingress-nginx-2.7.0","ingress-nginx-2.6.0","ingress-nginx-2.5.0","ingress-nginx-2.4.0","ingress-nginx-2.0.3","ingress-nginx-2.3.0","ingress-nginx-2.2.0","ingress-nginx-2.1.0","ingress-nginx-2.0.2","ingress-nginx-2.0.1","ingress-nginx-2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-15566.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","sco
