Office for Mac vulnerability

CERT has a recent warning for users of Office for Mac 2016 & 2019: Microsoft Office for Mac cannot properly disable XLM macros

There is a bug fix issued by Microsoft on 12 November.
The article does not mention earlier versions of Office
This seems like a low risk.

I would agree that this is currently a low risk as there have been no known attempts to exploit this vulnerability that was stumbled across and reported directly to Microsoft. That doesn’t mean it might not be used for malicious attacks at some point in the future against targets that use older versions of MS Office or are slow to install updates. There have been several similar attacks against small groups in poorly developed areas that often use legacy computers and applications.
