CVE-2026-50566
Fission: Environment Runtime.Container and Builder.Container SecurityContext bypass allows privileged pod creation
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon GHSA.
Description
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 containers in the Fission function or builder namespace, scheduled under the executor's high-privilege service account — enabling container-sandbox escape, host filesystem and network access, and potential node- and cluster-level compromise. This issue has been patched in version 1.24.0.
