This is the best summary I could come up with:

Mastodon has called admins to action following the disclosure of a critical vulnerability affecting the decentralized social network favored by erstwhile Twitter lovers.

Mastodon is a decentralized social network, meaning it runs on separate servers, independently owned and operated by their respective administrators.

For this reason, each instance of Mastodon requires an economy-of-scale to support its operations, including people to manage infrastructure and security engineering.

The good news for Mastodon users is that more than half of all active servers have already upgraded to the latest version in the space of a day, according to data from fediverse network stat collector FediDB.

Not only was Rochko’s advisory shared across different instances rapidly, but as screenshots of admin panels show, the platform itself also plastered clear warnings, making it fairly difficult to escape the urgent need to update.

“This introduces a vector for Cross-site-scripting (XSS) payloads that can be rendered in the user’s browser when a preview card for a malicious link is clicked through,” the advisory reads.

What are these horrible things in the picture? Are they made of plastic? What are they for?
