CVE-2026-50565
Fission builder pods auto-mount the fission-builder ServiceAccount token in the user-supplied builder container
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, Fission builder pods were created with ServiceAccountName: fission-builder and no AutomountServiceAccountToken: false, so the kubelet auto-mounted the service-account token into every container in the pod — including the user-supplied builder image. This issue has been patched in version 1.24.0.
