EPSS is a statistical estimate, not a certainty or a measure of impact. Combine it with CVSS, KEV status, exposure and your environment.
A security issue was discovered in ingress-nginx https://github.com/kubernetes/ingress-nginx where the `mirror-target` and `mirror-host` Ingress annotations can be used to inject arbitrary 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.)
This is a PoC code to exploit the IngressNightmare vulnerabilities (CVE-2025-1097, CVE-2025-1098, CVE-2025-24514, and CVE-2025-1974).
IngressNightmare POC. world first non-blind remote execution exploitation with multi-advanced exploitation methods. allow on disk exploitation. CVE-2025-24514 - auth-url injection, CVE-2025-1097 - auth-tls-match-cn injection, CVE-2025-1098 – mirror UID injection -- all available.
