No, none of the products from Arden utilise or are affected by the vulnerability exposed by Log4j.
Whilst we do use the log4net logging library, which is based on Log4j within the utility tool EnterpriseServicesStressTester and WEBcnx's Workflow Services application, this known vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.
