That is a cool feature, but that would mean that all of the web traffic would get returned to my local network (assuming that the server is set up on a remote VPS), which I really don't want to have happen. There is also the added downtime potential cause by the added point of failure of the GPU being hosted in a much more volatile environment (ie not, for example, a tier 3 data center).
Not all web traffic, just the images to check. With any decent bandwidth, it shouldn't be an issue for most. It also setup in such a way as to not cause a downtime if the checker goes down.
It's not only the bandwidth; I just fundamentally don't relish the idea of public traffic being directed to my local network.
You don't get public traffic redirected. It's not how it works
Yeah, that was poor wording on my part — what I mean to say is that there would be unvetted data flowing into my local network and being processed on a local machine. It may be overparanoia, but that feels like a privacy risk.
I don't see how it's a privacy risk since you're not exposing your IP or anything. Likewise the images are already uploaded to your servers, so there's no extra privacy risk for the uploader.
"Security risk" is probably a better term. That being said, a security risk can also infer a privacy risk.
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.
I will preface by saying that I am not casting doubt on your claim, I'm simply curious: What is the rationale behind why it would be so unlikely for such an exploit to occur? What rationale causes you to be so confident?
Image processing libraries are used at the forefront of almost all web services, including lemmy and are extraordinarily robust. I really don't have the time to go at this in depth, but if you are familiar with this stuff you will know how extraordinary such an exploit would be and its existence would be causing massive chaos all over the world.
Ah, yeah, my bad this was a lack of clarity on my part; I meant all image traffic.
Oh? Would the fallback be that it simply doesn't do a check? Or perhaps it could disable image uploads if the checker is down? Something else? Presumably, this would be configurable.
It stops doing checks. Iirc you can configure it yes
