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.

Earlier this month, we introduced the Imunify Security WordPress Plugin — designed to make the powerful protection of Imunify360 visible right inside the WordPress Admin Dashboard.

We’re excited to share that the Imunify platform—including ImunifyAV, ImunifyAV+, and Imunify360 — now fully supports Ubuntu 24. This compatibility extends to Plesk, DirectAdmin, Webuzo, and stand-alone setups, making it easier than ever for users on Ubuntu 24 to protect their servers with Imunify’s trusted security solutions.
