This flurry of activity is certainly going to have people be more apprehensive about unproven software that may be of dubious prominence. My question amid all of this is who else knew about these long-standing vulnerabilities?

cPanel is just about as far away from “unproven” as possible.

at the same time, I've never had any faith in that software.

maybe because of it's association with really cheap, buggy hosts i explored in my teenage years. maybe because of their largely unnecessary complications (except enterprise maybe). maybe because of the tendency of large bloated depressing organizations to use these even in places they shouldn't.

not that many software have faith in are faring any better in this cve-storm.

I think you misunderstood. My comment was meant to imply that people would be extra careful about all new software for a while. I know cpanel isn't unproven. It's been around forever.
