Kubernetes (K8s) is a system designed by Google for automating deployment, scaling, and management of containerized applications. It allows containers to run and be managed in a clustered environment, achieving high-efficiency deployment. Recently, four critical security vulnerabilities have been disclosed in Kubernetes ingress-nginx.

[CVE-2025-24514, CVSS: 8.8] This vulnerability allows the annotation of auth-url to be injected into nginx, potentially leading to arbitrary code execution within the ingress-nginx controller context and leaking data accessed by the controller.

[CVE-2025-1097, CVSS: 8.8] This vulnerability allows the annotation of auth-tls-match-cn to be injected into nginx, potentially leading to arbitrary code execution within the ingress-nginx controller context and leaking data accessed by the controller.

[CVE-2025-1098, CVSS: 8.8] This vulnerability allows the annotations of mirror-target and mirror-host to be injected into nginx, potentially leading to arbitrary code execution within the ingress-nginx controller context and leaking data accessed by the controller.

[CVE-2025-1974, CVSS: 9.8] This vulnerability allows an unauthenticated attacker to access the Pod network and execute arbitrary code within the ingress-nginx controller context, potentially leading to data leakage from the controller.
