CVE-Requests-1896609

CVE 请求 1896609 - feiskyer/mcp-kubernetes-server 执行摘要 本报告详细介绍了在 feiskyer/mcp-kubernetes-server 包中发现的两个严重安全漏洞。当部署该服务器时，它会暴露一个名为 kubectl 的 MCP 工具，旨在提供对 Kubernetes 集群的有限、安全访问。然而，不充分的输入验证允许两种不同的攻击向量： OS命令注入：攻击者可以通过使用 shell 元字符（例如 ,、;）链接命令来绕过命令验证，从而在运行 MCP 服务器的主机上执行任意 OS 命令...

PYSEC-2026-1619 mcp-kubernetes-server has a Command Injection vulnerability

mcp-kubernetes-server does not correctly enforce the --disable-write / --disable-delete protections when commands are chained. The server only inspects the first token to decide whether an operation is write/delete, which allows a read-like command to be followed by a write action using shell...

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...

CVE-2026-47250

CVE-2026-47250 concerns mcp-server-kubernetes, where the kubectl_generic tool exposes a flag-injection vulnerability due to passing user-supplied flags directly to kubectl without an allowlist. This can enable a privilege-escalation path in Kubernetes environments: an attacker with limited access...

Improper Authentication And Authorization

kubevirt.io/kubevirt is vulnerable to improper authentication and authorization. The vulnerability is due to improper validation of the Common Name CN field in client TLS certificates during mTLS authentication, which allows an attacker to bypass RBAC controls by impersonating the Kubernetes API...

CVE-2026-39884

The CVE-2026-39884 entry concerns mcp-server-kubernetes (Model Context Protocol server for Kubernetes) with a vulnerability in the port_forward tool (src/tools/port_forward.ts). The code builds a kubectl command by string concatenation using user-controlled input and naively splits on spaces befo...

yoke 访问控制错误漏洞

Yoke is a Kubernetes package management tool developed by YokeCD. Versions of Yoke prior to 0.19.0 contained an access control vulnerability. This vulnerability stemmed from the lack of proper authentication mechanisms in the Webhook endpoints of the Air Traffic Controller component, allowing any...

Command Injection

mcp-kubernetes-server is vulnerable to Command Injection. The vulnerability is due to the use of shell=True in the /mcp/kubectl endpoint, which allows an attacker to inject and execute arbitrary operating system commands...

EUVD-2025-201109

MCP Server Kubernetes is an MCP Server that can connect to a Kubernetes cluster and manage it. Prior to 2.9.8, there is a security issue exists in the execinpod tool of the mcp-server-kubernetes MCP Server. The tool accepts user-provided commands in both array and string formats. When a string...

Improper Command Restriction

mcp-kubernetes-server is vulnerable to improper command restriction. The vulnerability is due to incomplete validation of chained commands in the implementation of --disable-write and --disable-delete, which allows an attacker to bypass restrictions and execute unauthorized write or delete...

CVE-2025-59377

feiskyer mcp-kubernetes-server through 0.1.11 allows OS command injection, even in read-only mode, via /mcp/kubectl because shell=True is used. NOTE: this is unrelated to mcp-server-kubernetes and CVE-2025-53355...

CVE-2025-59376

feiskyer mcp-kubernetes-server through 0.1.11 does not consider chained commands in the implementation of --disable-write and --disable-delete, e.g., it allows a "kubectl version; kubectl delete pod" command because the first word i.e., "version" is not a write or delete operation...
