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 Container Executor Function PodSpec Injection Leading to Node Escape

Summary Fission's Container Executor path lets a tenant supply Function.spec.podspec directly; the executor merges it into the executor-built podspec and creates a Deployment whose pods run the user's container image. Details Two flaws compounded: 1...

GHSA-V455-MV2V-5G92 Fission Container Executor Function PodSpec Injection Leading to Node Escape

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...

Improper Privilege Management

Overview Affected versions of this package are vulnerable to Improper Privilege Management via the podspec parameter in the Container Executor path. An attacker can gain elevated privileges and potentially escape the node by supplying a crafted podspec that is merged into the deployment process...

CVE-2026-50564 Fission Environment CRD podspec passthrough enables hostPID/hostNetwork/privileged pods, node escape

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

CVE-2026-50564

CVE-2026-50564 concerns Fission’s Environment CRD prior to version 1.24.0, where spec.runtime.podSpec and spec.builder.podSpec were merged into runtime/builder pod specs without filtering. This allowed propagation of hostNetwork, hostPID, hostIPC, container privileged, and serviceAccountName from...

CVE-2026-50563

Fission before v1.24.0 allows a tenant to supply Function.spec.podspec, which is merged into the executor-built podspec and used to create a Deployment for the user’s container image. This directly explains the root cause of the listed vulnerability and aligns with the patched state in v1.24.0. T...
