Upgrade jupyter-enterprise-gateway to version 3.3.0 or higher.
Overview
jupyter-enterprise-gateway is an A web server for spawning and communicating with remote Jupyter kernels
Affected versions of this package are vulnerable to Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') via the rendering process of Kubernetes manifests using untrusted environment variables in Jinja2 templates. An attacker can inject arbitrary YAML content, overwrite critical fields such as securityContext, and create additional unintended Kubernetes resources by supplying specially crafted environment variables. This can result in the creation of privileged pods, arbitrary Kubernetes resources, and potentially full compromise of the Kubernetes cluster. This is only exploitable if the environment variables used in manifest rendering are controlled by the attacker, and in some cases, if the mirrorWorkingDirs configuration is enabled.
