CVE-2026-71567 User-controlled variables inserted unescaped into shell scripts and Kubernetes manifests

In openshift-metal3/fakefish there is a repeated pattern in some of the scripts where shell variables are injected without quoting them either into command lines or into manifests. This mostly applies to the Image URL and BMC credentials which are not verified by FakeFish...

CVE-2026-71567

CVE-2026-71567 affects openshift-metal3/fakefish , a tool used for provisioning bare-metal infrastructure. The vulnerability is a shell injection caused by unquoted shell variables being inserted into command lines and Kubernetes manifests. The primary attack vectors are the Image URL and BMC cre...

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...

CVE-2026-44182

CVE-2026-44182 affects Jupyter Enterprise Gateway before v3.3.0, where untrusted environment variables (KERNEL_XXX) are interpolated into Kubernetes manifests via a Jinja2 template without YAML-aware escaping. This YAML-injection can overwrite keys like securityContext, inject multi-document YAML...
