What to do about this

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

Fix it

Update Simple Cloudflare Turnstile to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Administrator multi-factor authentication in Hack Halt Pro blocks this class of attack before WordPress processes the request.

Require a second factor for every administrator account. This is the single highest-value control against credential stuffing and reused passwords, because a valid password alone stops being enough.
