Synopsis

The remote Kubernetes Ingress NGINX Controller is affected by an arbitrary code execution vulnerability.

Description

A security issue was discovered in Kubernetes where under certain conditions, an unauthenticated attacker with access to the pod network can achieve arbitrary code execution in the context of the ingress-nginx controller.
