GHSA-4HQQ-7Q79-932P

Vulnerability from github – Published: 2025-09-15 15:31 – Updated: 2025-09-25 20:46

Summary

mcp-kubernetes-server has an OS Command Injection vulnerability

Details

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 the server is running in read-only mode.

A remote, unauthenticated attacker can execute arbitrary OS commands on the host, resulting in full compromise of confidentiality, integrity, and availability.

This issue is distinct from mcp-server-kubernetes and from CVE-2025-53355.

Severity ?

9.8 (Critical)
