Elasticsearch 7.16.1 contains fixes for the Log4Shell security vulnerability, and we advise all users to upgrade to this version as soon as possible. See also the corresponding post from Elastic:

For older versions of Elasticsearch 7.x we recommend adding following JVM option manually:


In a standard Elasticsearch installation, this option can be added to
