What to do about this

Patch promptly The consequence is significant even where an attacker needs a foothold first.

Fix it

Update efore 1.26.8, UpdraftPlus to 1.26.8 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 efore 1.26.8, UpdraftPlus. Versions below 1.26.8 are vulnerable; that release and later are not. An attacker needs any registered account, so open registration materially increases the risk.

How do I fix it?

Update efore 1.26.8, UpdraftPlus to version 1.26.8 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 Broken Access Control flaw. An attacker who exploits it can reach actions or data that should have been restricted to someone else.

WordPress security that blocks attacks before they land.
