Hi,
 
  We are using Apache NiFi 1.7.0 and the security scan has high severity issues for Bouncy castle bcprov-jdk15on-1.59 and Apache‚Äôs commons-codec lib. How should we address them? The Bouncy Castle upgraded them to fix the issues. What about commons codec and are they available in 1.7.1? 
   
Thanks in advance.
