Hi @nisha,
Cool, that it worked
I’m sorry but we no longer support CrateDB 3.0.5 (released in July 2018❗️).
Regarding log4j I highly recommend to enable log4j2.formatMsgNoLookups
setting as explained in our info post. With this change you should be able to mitigate this specific vulnerability.
Furthermore I recommend to start planning and execute your upgrade path to update CrateDB to the most recent version.
