I have exactly the same issue: Script:SNH-gen [Trj]. I have made all possible checks, and my Wordpress- Website seems in fact to be fine, so I assume it's a false flag. The consequence is, that images don't load and in fact I cannot work on my website.
In my latest scan, Wordfence has found a vulnerability- issue on your plugin.
