The trick depends upon different implementations doing different things. Not likely for Word (though I suppose it is -possible- across different versions or different OSes).
Then you have people on Linux or macOS who might also use LibreOffice, Apples Office suite, or something else entirely.
And given MS Office is the de facto standard, you’ll often see people open OOXML documents within non-MS office suites.
After all, OOXML is an open standard (sarcasm).
ODF (the document formats favoured by most other office suites) is also ZIP-based XML. So they too could be vulnerable.
I do wonder, since a lot of tools outside of the MS ecosystem can read Office files (e.g. LibreOffice and Google Docs as well as plenty of other online tools), if indeed the hack as described by the article is possible. One would just need to figure out the ZIP stacks used by said tools.
