Phone home tracking image in DocuSeal, and how to remove it (www.reddit.com)

Kinda proud of this, so forgive me while I brag. I found a likely "phone home" tracking image in DocuSeal. I searched around: there was an extant issue about the image. I asked the devs: would they accept a PR to remove the image? A maintainer responded quickly that they were not interested in a PR to remove it, so I forked it in minutes with my tiny hack, built a new Docker image and re-deployed to my server after making a one-line change in a Docker Compose file.

Here's the hack: https://github.com/meonkeys/docuseal/commit/e710678d

Happy to share my compose config as well if folks are interested.

I do want to put in a plug for DocuSeal: they made an excellent thing. It's a fast and beautiful app for adding signatures to PDFs, similar to DocuSign or HelloSign, but awesomely AGPL licensed and easy to self-host. I got it running in minutes and it worked very well. I support what they're doing and I want to see them succeed. OpenSign looks cool too but I haven't tried that one yet.

So yeah. Self-hosting and FOSS FTW!

Loading external images will reveal to the site where it’s loaded from at least these things:

User’s IP
Useragent string
Referrer

Also it can set third-party cookies which can be used to track specific user.

I don’t know if this project processes any of that data, but outside images can be used for tracking purposes.

At least it would be a good idea to limit some of this things for that img tag by setting some attributes that prevent referrer and cookies from being sent.

AGAIN.

This is not "phoning home" as claimed. It is not a SECURITY RISK as claimed. It is a privacy want/complaint/nag at the very VERY least. THIS IS ALSO NOT A PRIVACY FOCUSED PROJECT.

Refer to the original comment, and realize this was being run in a container. So, what...it's a risk to have libcurl ide tidied on your server? Your IP address is so damn private and important? Literally nobody cares.

Y'all need to get better hobbies, seriously. Probably just need to get off the Internet if this is the stuff causing consternation in your lives.
