I am able to get the base64 data using background script in global scope

You can check the script and enhance

I believe if the base64 string is huge then it might not work while setting the response of scripted rest api

var attGr = new GlideRecord('sys_attachment');
  attGr.addQuery('sys_id', 'b45f80356f102100758ecb512e3ee485');
  attGr.query();
  if(attGr.next())
        {
   var gsu = (typeof GlideStringUtil != 'undefined') ? (GlideStringUtil) : (Packages.com.glide.util.StringUtil); //few versions support the first one, other supports second
   var gsa = (typeof GlideSysAttachment != 'undefined') ? (new GlideSysAttachment()) : (new Packages.com.glide.ui.SysAttachment());
   var attachmentData = gsa.getBytes(attGr);
   var attachment = String(Packages.java.lang.String(attachmentData));
   gs.info(attachment); //the data in the file will be printed as String
   var encData = GlideStringUtil.base64Encode(attachmentData); // data of one attachment at a time
   gs.info(encData);
}

Output:
