Prior to 1.51.0, the @zuke/core MCP registry mode accepts command-form registry descriptors without applying the ZUKE_REGISTRY_LAUNCH_HOSTS authorization enforced for remote module descriptors. When zuke mcp --registry --allow-run reads a registry writable by another party and a run-capable caller invokes the affected tool, the registry writer can choose the program and arguments executed with the operator's environment and workspace access.
