=== Enhancements | ||
|
||
* Add log4j2.formatMsgNoLookups logging property to ES < 7.2 {pull}5157[#5157] | ||
|
||
This change will mitigate the link:https://github.com/advisories/GHSA-jfh8-c2jp-5v3q[Log4Shell] vulnerability (CVE-2021-44228) in susceptible Elasticsearch clusters (below version `7.2`). ECK will prepend the `-Dlog4j2.formatMsgNoLookups=true` JVM parameter to the environment variable `ES_JAVA_OPTS`` if it is not yet defined by the user. This triggers a rolling restart of all Pods of the affected Elasticsearch clusters to apply these changes. | ||

* Add internal product header to requests {pull}5129[#5129] | ||
