Hi there -
As you've surely read, a major vulnerability was found in a ubiquitous software package called Log4j. You can read more about that here.
As a security measure, our team has conducted a full impact assessment, evaluating all of our staging and production systems. We do not use the log4j library and thus we have not been impacted by the vulnerability.
We are constantly monitoring the response of security researchers to observe the further discovery of this vulnerability and other that may arrive. Further updates will be posted here as necessary.
