Is anyone else seeing wide-scale SQL injection attacks?

I host a number of sites for my clients, and over the past few days, I've been seeing a ton of attack attempts, across all of my sites. I'm pretty used to the normal noise, so it wasn't surprising that everything started ramping up after the latest WordPress CVEs, for example. However, I'm getting a lot of SQL injection style attacks as well--way more than background noise, and hitting all of my sites around the same time (or more accurately, consistently).

Is anyone else seeing this (i.e., it's a broad-scale campaign), or is it limited to me?
