CVE-2026-0759Network attack vector

Unauthenticated code execution via executeCommand injection

Published Jan 23, 2026 · Updated Jan 23, 2026

Command injection in Katana Network Development Starter Kit allows remote attackers to execute code through its Foundry MCP server. The executeCommand method passes an insufficiently validated user-supplied string into a system call, running commands as the service account. The vendor disputes applicability, and upstream documentation presents the server as a locally launched stdio process rather than a network listener.
