No, Tm Master v2 is not affected by the Apache Log4j vulnerability.
Apache Log4j is part of the Apache Logging Project. By and large, usage of this library is one of the easiest ways to log errors, and that is why most Java developers use it.
TM Master v2 does not use the Log4j library (TM Master v2 is not written In Java) and hence TM Master v2 is not vulnerable to the Log4j exploit.
Tero Marine recommends that customers using software utilizing Apache Log4j ensure that their Log4j version is upgraded to 2.15.0 or newer.
