GHSA-M63V-2G9W-2W6V Fission: Environment Runtime.Container and Builder.Container SecurityContext bypass allows privileged pod creation

Summary A follow-up bypass of the round-4 PodSpec hardening GHSA-gx55-f84r-v3r7, GHSA-wmgg-3p4h-48x7, GHSA-v455-mv2v-5g92. Those advisories validate and sanitize the PodSpec spec.runtime.podSpec / spec.builder.podSpec / function.spec.podSpec, but the Environment CRD also exposes...

GHSA-GX55-F84R-V3R7 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. The merge logic propagated hostNetwork, hostPID, hostIPC, container privileged, and serviceAccountName from the user-supplied podsp...

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...
