CVE-2021-25748

Date: May 23, 2023

A security issue was discovered in ingress-nginx where a user that can create or update ingress objects can use a newline character to bypass the sanitization of the "spec.rules[].http.paths[].path" field of an Ingress object (in the "networking.k8s.io" or "extensions" API group) to obtain the credentials of the ingress-nginx controller. In the default configuration, that credential has access to all secrets in the cluster.
