I wonder if the companies that forked mastodon (like truth social) will bother to update. I can see someone posting stuff as a former president with this flaw.

Eh, stuff like truth social doesn't federate with anything anyway, so unfortunately this isn't a vulnerability for them.

Has it been confirmed this is a federation bug?

[-] NOT_RICK@lemmy.world 37 points 2 years ago

Is this mastodon specific or is it an activitypub flaw?

[-] Zak@lemmy.world 31 points 2 years ago

we think any amount of detail would make it very easy to come up with an exploit

People who would create exploits for this definitely can't read the diffs and see what changed.

Every barrier that slows down attacks a little is worth it when you are trying to buy time so people can apply emergency updates. It's not about stopping them from ever figuring it out.

Depends on skill level and the exact nature of the flaw. There's definitely going to be a nonzero number of malicious people who lie in the middle distance "I can come up with a way to exploit flaws if I have a detailed trail of breadcrumbs" and "I can't be bothered to do an unlimited amount of work to track down how to do this, I have other malicious things on my schedule for today."
