We are using Elasticsearch as a log server for Liferay application 7.3-ga1.  
The recommended version of ELS is 7.12 as per Liferay documentation.

Recently I have scanned the docker image with Azure Defender and observed this CVE-2021-20305 vulnerability issue.

This is a potential vulnerability and a red flag for docker image - for more details refer following link - [CVE - CVE-2021-20305](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-20305)
