editEnhancements
edit- 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.
- Add internal product header to requests #5129
Bug fixes
edit- Resource aggregator should handle missing memory settings #5158
Misc
edit- Update golang Docker tag to v1.17.5 #5149
