Just a lvl 28 guy from Finland. Full-stack web developer and Scrum Master by trade, but actually more into server-side programming, networking, and sysadmin stuff.

During the summer, I love trekking, camping, and going on long hiking adventures. Also somewhat of an avgeek and a huge Lego fanatic.

A furry or something. Why be yourself when you can be a fluffy raccoon on the internet?

  • That’s reassuring to know. What I don’t understand is why you have the /api/v3/post/like/list route. You say you don’t want votes to be snooped on, but then you add an endpoint that makes it very easy for instance admins to do exactly that if they choose to? Also worth pointing out that the tool linked here wouldn’t work in its current form if this route didn’t exist.

    Compare your actions to releasing a 0-day exploit for a security vulnerability instead of responsibly disclosing. It doesn’t help, it just causes chaos until the people who do the actual work can figure out a solution.

    This comparison is not fair at all. It’s not like the devs are unaware of this. They could start by removing the API endpoint that lists a post’s votes, but they haven’t, which means they seem to think it’s okay for the instance admins to snoop on votes if they so wish.


  • They can include runnable JavaScript too, which can cause vulnerabilities in certain contexts. One example from work some years back: We had a web app where users could upload files, and certain users could view files uploaded by others. They had the option to download the file or, if it was a file type that the browser could display (like an image or a PDF), the site would display it directly on the page.

    To prevent any XSS (scripts from user-provided files), we served all files with the CSP sandbox header, which prevents any scripts from running. However, at the time, that header broke some features of the video player on certain browsers (I think in Safari, at least), so we had to serve some file types without the header. Mistakenly, we also included image files in the exclusion, as everyone through image files couldn’t contain scripts. But the MIME type for SVG files is image/svg+xml… It was very embarrassing to have such a simple XSS vuln flagged in a security audit.
