Description

Unpatched vulnerabilities in publicly accessible applications can increase the likelihood of exposing weaknesses, creating an entry point for attackers to gain unauthorized access to the pod or container. Granting excessive capabilities to a pod or container can lead to unintended lateral movement to other containers or to the underlying node resources.

Remediation

Review any associated vulnerability references or advisories.
Apply the appropriate patch based on remediation guidance. If no patch is available, apply compensating controls such as disabling or removing the vulnerable component.
Review your Kubernetes pod or container security context configurations to ensure they provide proper isolation boundaries. Possible mitigations include using Kubernetes Pod Security Policies, SELinux, AppArmor, or Seccomp filters.
