GHSA-4hqq-7q79-932pCriticalCVSS 9.8
mcp-kubernetes-server has an OS Command Injection vulnerability
🔗 CVE IDs covered (1)
📋 Description
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.
