There's [this blog post](https://www.elastic.co/blog/log4j2-vulnerability-what-to-know-security-vulnerability-learn-more-elastic-support) and [this announcement](https://discuss.elastic.co/t/apache-log4j2-remote-code-execution-rce-vulnerability-cve-2021-44228-esa-2021-31/291476). They should be readily available on all major search engines - for instance here on [Google](https://www.google.com/search?q=elastic+log4j+vulnerability).
