PYSEC-2026-3817 Trestle has Server-Side Template Injection (SSTI) via Recursive Template Re-evaluation of Untrusted Data

Impact A Server-Side Template Injection SSTI vulnerability exists in multiple locations of trestle's Jinja2 rendering pipeline due to a systemic pattern: untrusted data is re-parsed as Jinja2 template source code without sandboxing. This advisory tracks the root cause across all affected code...

CVE-2026-44182 Jupyter Enterprise Gateway Has Kubernetes Manifest Injection via Jinja2 Template Rendering

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., KERNELXXX into Kubernetes manifests without YAML-aware escapin...

Jupyter Enterprise Gateway: Jinja2 Template Server Side Template Injection resulting in Remote Code Execution

Summary The environment variables KERNELXXX used during the rendering of the Kubernetes manifest are vulnerable to Server Side Template Injection SSTI. By including Jinja2 template expressions it is possible to execution Python code and OS Commands in the Enterprise Gateway service. The code can...
