CWE: CWE-918 \u2014 Server-Side Request Forgery (SSRF)
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.

Code:
	public CommandExecutionResult openNetwork(String name) {
		if (initDone == false)
			return errorNoInit();

		if (currentGroup() != null)
			return CommandExecutionResult.error("Cannot open network in a group");

		for (NStackable element : stack)
			if (element instanceof Network)
				return CommandExecutionResult.error("Cannot nest network");

		if (networks.size() == 0 && groups.size() == 0)
			eventuallyConnectAllStandaloneServersToHiddenNetwork();

		final Network network = createNetwork(name);
		stack.add(0, network);
		return CommandExecutionResult.ok();
