Elasticsearch doesn't enforce HTTPS traffic.

Property	Value
Language
Severity
Service	elastic-search
Provider	AWS
Vulnerability Type	omission

Description

Plain HTTP is unencrypted and human-readable. This means that if a malicious actor was to eavesdrop on your connection, they would be able to see all of your data flowing back and forth.

You should use HTTPS, which is HTTP over an encrypted (TLS) connection, meaning eavesdroppers cannot read your traffic.

Resolution

Enforce the use of HTTPS for ElasticSearch
