I have reviewed the code and it looks like you are correct. There is no handling for guest users.

Try this. In includes/ces_permissions.php, find:

	if (!empty($parser->ces_options["$forumid"][$parser->ces_options['current_userid']]))
	{
		$dohtml = $parser->ces_options["$forumid"][$parser->ces_options['current_userid']]['can_html_' . $parser->ces_options['check_type']];

Before it, add:

	if (empty($parser->ces_options['current_userid']))
	{
		// user is a guest
		$userinfo = array(
			'userid' => 0,
			'usergroupid' => 0,
			'membergroupids' => ''
		);

		if (empty($parser->ces_options["$forumid"][0]))
		{
			if (empty($post['permissions']))
			{
				$grab = true;
			}
			else
			{
				$userinfo['permissions'] = $post['permissions'];
			}
		}
	}
