Summary
Improper Neutralization of Special Elements Used in a Template Engine in Kibana Workflows Leading to Server-Side Request Forgery (SSRF)
Details

Improper Neutralization of Special Elements Used in a Template Engine (CWE-1336) exists in Workflows in Kibana which could allow an attacker to read arbitrary files from the Kibana server filesystem, and perform Server-Side Request Forgery (SSRF) via Code Injection (CAPEC-242).
