Important Vulnerability on Advanced Custom Fields Plugin for WordPress

There are moments every server admin dreads. Like when your security tool blocks a file that you know is safe, and when you find a suspicious file that your tool missed entirely.

False positives are frustrating disruptions that can break a site and create support tickets, while false negatives cause a nagging uncertainty that leaves you wondering what else might be lurking undetected. In both cases, you want to report it because you want the system to get smarter.

But previously, submitting a file for analysis might have felt like sending it into a black hole. You do your part, but you never find out what happens next. Was it reviewed? Was it a true threat? Could it be included in the next signature update?

Now, we’re changing that.

When we launched the Imunify Security WordPress Plugin, our goal was clear: make security visible to site owners by showcasing the protection hosting providers deliver with Imunify360.

After rapidly reaching 50,000 installations, we are excited to share that over 260,000 WordPress websites now have the plugin installed and active.

And now, we're ready for V2.
