Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.
You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.
What is this endpoint?
elastic/api/_cluster/health
Elasticsearch Cluster Health API
What an attacker could do
An open Elasticsearch cluster API discloses node and shard topology and signals an unauthenticated cluster, allowing an attacker to read, modify, or delete indexed data and trigger ransom wipes.
How to defend it
Enable the security features (authentication and TLS), bind to private interfaces, and place the cluster behind a network policy or authenticated gateway.
