"Mastodon vulnerability allows attackers to take over accounts"
Snopes: Mixed
It's a serious vulnerability for sure: "allowing attackers to impersonate users and take over their accounts"
But while this part is true: "allowing attackers to impersonate users"
This part is exaggerated: "and take over their accounts"
Impersonating remote users doesn't allow you to log in as them, change their email or password, etc. It allows people to submit forged posts by them, and "trick" Mastodon servers into accepting it. Either way, interesting that this leaks into the wider web.
@arcanicanis@Dan_Ramos It's pretty awesome. But I stand by my statement that "taking over accounts" is an exaggeration, because you cannot actually log in as them or change their password. Impersonation is a critical security issue. But people should not believe this can let people lock them out of their account.
Well, it’s really close in severity: when you can take over the deliverability of their posts to any followers (on any software) that aren’t on the same server, when you can take over where Direct Messages across servers end up, when you can change the public key cached for any remote user and start impersonating S2S traffic, and much more.
