PYSEC-2026-363 Jupyter Enterprise Gateway: ContainerProcessProxy._enforce_prohibited_ids Bypass

Summary Jupyter Enterprise Gateway has a prohibited UID and GID feature that by default prevents launching kernels with UID or GID 0 root. This can be bypassed. It is possible to launch kernels with a prohibited UID and/or GID by using a specially crafted KERNELUID or KERNELGID value. The feature...

PYSEC-2026-409 mcp-kubernetes-server has an OS Command Injection vulnerability

feiskyer/mcp-kubernetes-server through 0.1.11 allows OS command injection via the /mcp/kubectl endpoint. The handler constructs a shell command with user-supplied arguments and executes it with subprocess using shell=True, enabling injection through shell metacharacters e.g., ;, &&, $, even when...

github.com/containerd/containerd: containerd: Denial of Service via maliciously crafted image leading to unbounded group parsing

A flaw was found in containerd, an open-source container runtime. A remote attacker could exploit this vulnerability by providing a maliciously crafted image. When a container is created from this image, it leads to uncontrolled resource consumption and memory exhaustion, causing the containerd...

github.com/containerd/containerd: containerd: Security bypass via Container Device Interface (CDI) annotation smuggling during checkpoint restoration.

A flaw was found in containerd, an open-source container runtime. The Container Runtime Interface CRI implementation, which allows Kubernetes to interact with container runtimes, improperly trusts Container Device Interface CDI annotations found within untrusted checkpoint image metadata during...
