What to do about this

Patch on your next cycle Worth fixing, but not ahead of other work.

Fix it

Update WordPress Core to 4.5.3 or later.

That is the complete fix. Everything below is what protects you in the meantime.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.

Am I affected by this vulnerability?

You are affected if your site runs WordPress Core. Versions below 4.5.3 are vulnerable; that release and later are not.

How do I fix it?

Update WordPress Core to version 4.5.3 or later. That is the complete fix. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

What can an attacker actually do?

This is a Cross-Site Scripting (XSS) flaw. An attacker who exploits it can run script in a visitor's browser, stealing sessions or planting an administrator account.

WordPress security that blocks attacks before they land.
