Am I affected by this vulnerability?

You are affected if your site runs WordPress component. No account is needed to exploit this, so a public site is reachable by anyone.

How do I fix it?

What can an attacker actually do?

This is a Information Disclosure flaw. An attacker who exploits it can read data they were never meant to see, which is often the first step in a larger attack.
