Hello,  
Our centralized logging will undergo some vulnerability tests by third party auditors.  
I want to know whether following security issues does exist with ELK.? How to test them?

1. XML external entity injection : Does it possible in case of HTTP logstash input?
2. Denial of Service attack vulnerability
3. Persistent cross-site scripting
4. Reflected Cross-Site Scripting

br,
