Why would it be a security risk?
For clarity, I’m not claiming that it would, with any degree of certainty, lead to incurred damage, but the ability to upload unvetted content carries some degree of risk. For there to be no risk, fedi-safety/pictrs-safety would have to be guaranteed to be absolutely 100% free of any possible exploit, as well as the underlying OS (and maybe even the underlying hardware), which seems like an impossible claim to make, but perhaps I’m missing something important.
You mean an exploit payload embedded in an image, and pwning a system parsing that image through python PIL? While there’s never a 100% chance of anything, you’re more likely to be struck by lightning than this coming to pass and at that point you’re at more security risk at using the internet altogether.
