Hello @lostwizard,
It was a false positive, but we have already fixed this issue. Please, synchronize the plugin:
• WordPress Admin Page → Settings → Security by CleanTalk → Synchronize with Cloud
Did it help?
I synchronized and re-ran the scan. It cleared the problem.
We are glad to know the issue is solved.
If you have a moment, could you please leave us some feedback? We would be very grateful: https://projectdmc.org/support/plugin/security-malware-firewall/reviews/
