- Summary
- Ingress-nginx `path` sanitization can be bypassed with newline character
- Details

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[].pathfield of an Ingress object (in thenetworking.k8s.ioorextensionsAPI group) to obtain the credentials of the ingress-nginx controller. In the default configuration, that credential has access to all secrets in the cluster. - Database specific
