Fission Environment CRD podspec passthrough enables hostPID/hostNetwork/privileged pods, node escape

Summary Fission's Environment CRD exposes spec.runtime.podSpec and spec.builder.podSpec, which are merged into the Kubernetes pod specs for runtime and builder pods.

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

Summary A stronger framing of the same root cause as GHSA-gx55-f84r-v3r7: the Environment.spec.runtime.podSpec / spec.builder.podSpec passthrough lacked validation, and MergePodSpec propagated dangerous fields into the generated pods. Details Three independent flaws compounded: 1. Validate gap...
