These are the reason, why every easily reachable web server will be spammed with /something/something.php?somearg=someval. If I had to guess, which software on the web has been the most exploitable over all of the web's history, WP would surely be among the top candidates. Maybe right after MS Teams or Sharepoint or some stuff like that.
TBF, some of it is structural: if you're the most popular anything on the internet, you'll be the most attacked and the most exploited, and hence the most exploitable.

And its closely related cousin, Joomla.
The access log of public http servers is truly interesting to watch.
You know that the scripts doing it are optimized for success rate, so the types of requests they send give you an impression of what's actually out there.
It's clear to me that once we finally achieve rogue AGI, it is going to propagate through unpatched WordPress WooCommerce instances.
