Tested a few different ways on a few different devices and the “issue” is consistently the same: if you simply share one image at a time — the image that you’re editing — VSCO app is simply unusable, VSCO insists that I needs permissions to your full gallery of images to function.
Similar ‘editing exercises’ could be done on multiple other iOS photo editor apps, with a single photo permission with no issues.
This issue exists even the latest update that came overnight.
