**Elasticsearch information disclosure (ESA-2018-19)**

Elasticsearch Security versions 6.5.0 and 6.5.1 contain an XXE flaw in Machine Learning’s find\_file\_structure API. If a policy allowing external network access has been added to Elasticsearch’s Java Security Manager then an attacker could send a specially crafted request capable of leaking content of local files on the Elasticsearch node. This could allow a user to access information that they should not have access to.

Please note: by default Elasticsearch has the Java Security Manager enabled with policies which will cause this attack to fail.

**Affected Versions**  
Elasticsearch Security versions 6.5.0 and 6.5.1

**Solutions and Mitigations**  
Affected users should upgrade to Elasticsearch version 6.5.2.

**CVE ID: CVE-2018-17247**
