What Are Some of the Worst WordPress Security Issues?

A real big thing to have is you need to have a web application firewall. Cloudflare is a CBN, which can increase performance by loading files closer locally to wherever you are. And so that can take any security hits and kind of stop it before it even gets to the host. People will go on like theme forest or co-canyon is their plugin version of it. But they don't keep up with their WordPress updates. So an out of date plugin causing some type of vulnerability.
