SUSE CVE-2026-50545

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...

SUSE CVE-2026-50563

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 Container Executor path lets a tenant supply Function.spec.podspec directly; the executor merges it into the...

GHSA-QF5V-M7P4-95RP Fission: Incomplete capability denylist in Environment/Function PodSpec validation allows tenant-added CAP_SYS_TIME and cross-tenant node wall-clock corruption

Fission v1.24.0 added PodSpec safety validation for tenant-facing Environment and Function CRDs ValidatePodSpecSafety / ValidateContainerSafety admission webhook + sanitizeContainerSecurityContext executor merge layer, but the capability check was implemented as a fixed denylist of six Linux...

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...

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...

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...

GHSA-7M8X-QG2J-4M3V Fission: MessageQueueTrigger scaler manager materializes Secret values into Deployment envvars and accepts arbitrary user PodSpec

Summary The Fission MessageQueueTrigger MQT scaler controller exposed two privilege-escalation primitives to any subject able to create MQTs in a namespace. Details 1. Secret materialization. getEnvVarlist in pkg/mqtrigger/scalermanager.go read the Secret named in Spec.Secret using the controller...

Improper Privilege Management

Overview Affected versions of this package are vulnerable to Improper Privilege Management via the MergePodSpec process. An attacker can gain unauthorized access to cluster nodes and potentially take control of the entire cluster by injecting malicious fields into the podSpec configuration...
