Check your site today
In your WordPress dashboard, go to Tools, then Site Health, then Info, then Server to see your PHP version.
The fixed versions are 8.5.12, 8.4.27, 8.3.36 and 8.2.35, or your host's own patched package. Ask your host to confirm in writing that the patch is installed.

The site we build for you is plain files served from your own Cloudflare account. No PHP runs on it, so a flaw like this has nothing to attack, and you stop waiting on a host's patch schedule.
A new site does not remove an existing compromise. If you suspect yours was hit, tell us and we scan before we move anything.
