title: Aurora is allowing writes to read only endpoint
body: <p>I recently set up an Aurora RDS database and the default Writer roles shows two endpoints:</p>
  
  <p>1) Writer
  2) Reader</p>
  
  <p>However when I access with the Reader endpoint I am still able to update records on the database.</p>
  
  <p>Can someone explain why this is behaving this way?</p>
