Official Description

MCP Server Kubernetes before 3.9.0 contains an argument injection vulnerability in structured tools (kubectl_get, kubectl_describe, kubectl_delete) that allows attackers to bypass the assertNoDangerousFlags security check by supplying resourceType and name parameters with leading dashes. Attackers can inject the --server flag to redirect kubectl commands to an attacker-controlled API server, causing the operator's bearer token to be transmitted externally and enabling full cluster compromise.

Risk Analysis

This critical vulnerability in MCP Server Kubernetes allows an unauthenticated remote attacker to inject arguments into structured tools, bypassing security checks. With a CVSS score of 9.8 (Critical), this flaw poses an extremely high risk, potentially leading to full cluster compromise by exfiltrating the operator's bearer token.

No public exploit is currently known for this vulnerability. However, its remote exploitability (AV:N) and low attack complexity make it a significant concern.

Recommended Action

Administrators should upgrade MCP Server Kubernetes to version 3.9.0 or later to mitigate this argument injection vulnerability. Implement strict input validation for all parameters supplied to kubectl commands to prevent malicious flag injection.

Technical Analysis

CVE-2026-61459 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
