CVE-2026-49823

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, a Fission Function spec carries three reference types — Secret, ConfigMap, and Package. The first two were namespace-validated by...

CVE-2026-49824

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 Fission Function admission webhook pkg/webhook/function.go validated that spec.secrets.namespace and spec.configmaps.namespace...

CVE-2026-46614

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.23.0, the Fission router registers an internal-style route — /fission-function/ and /fission-function// — for every Function object,...

CVE-2026-50570

Fission prior to v1.25.0 allowed tenant-created Function/Environment CRDs to request securityContext.capabilities.add: ["SYS_TIME"] despite a fixed denylist (SYS_ADMIN, NET_ADMIN, SYS_PTRACE, SYS_MODULE, DAC_READ_SEARCH, DAC_OVERRIDE). The validation/merge-layer sanitization did not block CAP_SYS...

CVE-2026-50570 Fission: Incomplete capability denylist in Environment/Function PodSpec validation allows tenant-added CAP_SYS_TIME and cross-tenant node wall-clock corruption

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.25.0, Fission added PodSpec safety validation for tenant-facing Environment and Function CRDs ValidatePodSpecSafety /...

CVE-2026-50566 Fission: Environment Runtime.Container and Builder.Container SecurityContext bypass allows privileged pod creation

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, a tenant with environments.fission.io create/update RBAC can run privileged / allowPrivilegeEscalation / dangerous-capability...

CVE-2026-50563 Fission Container Executor Function PodSpec Injection Leading to 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 Container Executor path lets a tenant supply Function.spec.podspec directly; the executor merges it into the...

CVE-2026-49824

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes.

CVE-2026-49824

Fission (Kubernetes-native serverless framework) prior to v1.24.0 allowed a cross-namespace environment reference via the Function admission webhook because spec.environment.namespace was not validated, unlike spec.secrets[].namespace and spec.configmaps[].namespace. The issue affects the Functio...

CVE-2026-49823 Fission: Cross-namespace Package read via unvalidated PackageRef in Function admission webhook

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes.
