What to do about this

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

Fix it

Update Xpro Addons to 1.7.4 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.

Not sure if you are affected?

Scan your site to see whether it runs Xpro Addons, and at which version.

Free, no installation, no account. It reads what your site already publishes, then tells you which plugins carry known vulnerabilities and what to do about each one.

Am I affected by this vulnerability?

You are affected if your site runs Xpro Addons. Versions below 1.7.4 are vulnerable; that release and later are not. An attacker needs contributor or above, so open registration materially increases the risk.

How do I fix it?

Update Xpro Addons to version 1.7.4 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.
