CVE-2025-1098 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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. EPSS estimates a 83.07% chance of exploitation in the next 30 days.
