Fission Environment CRD PodSpec Injection Leading to Node Escape and Cluster Takeover

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.24.0, the Environment.spec.runtime.podSpec / spec.builder.podSpec passthrough lacked validation, and MergePodSpec propagated dangerous fields into the generated pods. This issue has been patched in version 1.24.0.
