Preliminary research

Jupyter Enterprise Gateway - From Notebook to Kubernetes Cluster Admin

Ben Cambourne · elttam

AI-collected research leads through 22 September 2026, including targeted additions between broader sweeps. Unranked, incomplete, not community-vetted, and subject to change.

Traces Jupyter Enterprise Gateway inputs through three paths: numeric coercion around a UID/GID denylist, explicit Jinja template evaluation and unescaped YAML pod specifications. The walkthrough distinguishes execution in the gateway from execution in a kernel pod and shows how mounts and service-account privileges affect the resulting access.
