Vulnerability Title
Jupyter Enterprise Gateway Has Kubernetes Manifest Injection via Jinja2 Template Rendering
Vulnerability Description
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.

Jupyter Enterprise Gateway 输入验证错误漏洞
Vulnerability Description
Jupyter Enterprise Gateway是Jupyter组织的一款网络设备产品。 Jupyter Enterprise Gateway 3.3.0之前版本存在输入验证错误漏洞,该漏洞源于服务器在将不可信的环境变量(如KERNEL_XXX)插入Kubernetes清单时未进行YAML感知的转义,可能导致YAML注入攻击。攻击者可注入新字段、覆盖关键字段(如重复securityContext键,最后一个生效),并注入文档边界(---代表新文档,...代表文档结束)以生成多个资源,可能创建任意类型,
