CVE-2026-61459: Suyogs Mcp-Server-Kubernetes

Critical severity, CVSS 9.8. EPSS: 2.4% chance of exploitation in the next 30 days.

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.

Affected products

• Suyogs Mcp-Server-Kubernetes: before 3.9.0 (fixed in 3.9.0)
