Are there any recommendations from Elastic regarding [NVD - CVE-2021-44228](https://nvd.nist.gov/vuln/detail/CVE-2021-44228)), a very serious log4j vulnerability announced today?

See: [CVE-2021-44228 aka log4shell is logstash and/or elasticsearch affected? - #9 by BenB196](https://discuss.elastic.co/t/cve-2021-44228-aka-log4shell-is-logstash-and-or-elasticsearch-affected/291415/9) and [Zero-day-exploit in log4j2 which is part of elasticsearch - #6 by BenB196](https://discuss.elastic.co/t/zero-day-exploit-in-log4j2-which-is-part-of-elasticsearch/291439/6)

Also, I think Elastic Security is the wrong section for this topic.
