CVE-2024-7646: [kubernetes] CVE-2024-7646: Ingss-nginx Annotation Validation Bypass
First published: Fri Aug 16 2024(Updated: )
A security issue was discovered in ingress-nginx where an actor with permission to create Ingress objects (in the `networking.k8s.io` or `extensions` API group) can bypass annotation validation to inject arbitrary commands and obtain the credentials of the ingress-nginx controller. In the default configuration, that credential has access to all secrets in the cluster.
