Got a mail from one of the authors of freewvs, “a free web vulnerability scanner”, which is also a built-in feature of Schokokeks.org Webhosting, that they’ve just added ClassicPress version testing to the script 
Rough translation:
“Hello, (…) I’ve found this mail by chance … Sorry for not responding earlier, but I’ve just added classicpress-support to freevws”
