MODERATORS
This bug was a result of the way that Mastodon handled file uploads. Because of the way that Mastodon attempted to figure out what kind of file that a user uploaded, it was possible to create a very specific type of multimedia file that would, when analyzed by the server, trick the server into executing its contents like code rather than an image or movie file. Unless Lemmy processes files the same way, Lemmy should be unaffected.
