It appears as the staticperl from camerarawpreviews is being flagged as a trojan by some EPP.
I can’t find any comments regarding this being a false positive or not.
Hope to gain some input about it here.
Thanks for the report. I see no file called staticperl inside the snap.
$ unsquashfs -l nextcloud_22327.snap | grep staticperl
This suggests to me this is an external additional binary installed on your system as an extra app (hint in the path)
/extra-apps/, rather than something delivered in the snap itself. This could be an issue you may want to report to the upstream NextCloud developers, or to the maintainer of the camerarawpreviews addon here. https://apps.nextcloud.com/apps/camerarawpreviews
