What to do about this

Patch immediately Serious, and reachable without meaningful privilege.

Fix it

Update Quick Chat to 4.00 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 Quick Chat. Versions below 4.00 are vulnerable; that release and later are not.

How do I fix it?

Update Quick Chat to version 4.00 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 SQL Injection flaw. An attacker who exploits it can read, alter or delete anything in the site database, including user accounts and password hashes.

WordPress security that blocks attacks before they land.
