Firewall Blocking file uploads Suspicious SQL code detected

Hello, I use an addon called Lumise, it allows users to upload images and add them to a product for sale, but the Traffic Inspection blocks them with =

IP blocked Attempt to upload a file with malicious code
Attempt to upload malicious file denied Suspicious SQL code detected

The Firewall inspection mode has to be disabled, then people can add images

Any advicewould be appreciated
