Elastic Cloud on Kubernetes version 1.9.1edit
Enhancementsedit
- Add log4j2.formatMsgNoLookups logging property to ES < 7.2 #5157
This change will mitigate the 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.
