SCA: security update for jupyter_enterprise_gateway (GHSA-cfw7-6c5v-2wjq)

critical Tenable Cloud Security Plugin ID 442608

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Jupyter Enterprise Gateway launches remote Jupyter Notebook kernels across distributed clusters like
 Apache Spark, Kubernetes, and Docker Swarm. In versions prior to 3.3.0, the server interpolates untrusted
 environment variables (e.g., KERNEL_XXX) into Kubernetes manifests without YAML-aware escaping, enabling
 YAML injection attacks. Attackers can inject new fields, overwrite critical fields (e.g., duplicate
 securityContext keys, where the last one prevails), and inject document boundaries (--- for new documents,
 ... for end-of-document) to generate multiple resources, potentially creating arbitrary types, such as
 privileged pods. The Jinja2 template for the Kubernetes manifest contains several kernel_xxx variables,
 such as kernel_working_dir that are used when rendering the manifest and are all vectors for YAML
 injection. This issue has been fixed in version 3.3.0. (CVE-2026-44182)

Solution

Update the jupyter_enterprise_gateway library and its related packages to version 3.3.0 or later.
