Elastic Batch Platform & deployed applications
We do not bundle the Log4J components in the Elastic Batch Platform (EBP), or in replatformed batch or online application packages (jars, wars, ears). There are no required changes to either your EBP installation or application packages built with default components.
However, if you have manually added Log4J 2.x components in your application packages you should update them to the latest available jar via the links above.
