Yeah, there’s also this:

A more recent issue came about when Pixelfed’s creator, Daniel Supernault made the details of a vulnerability public before server operators had a chance to update, which would have left the fediverse vulnerable to bad actors, she says. (Supernault has already apologized publicly for his handling of the issue that had affected private accounts.)

In the case of the Pixelfed issue, for instance, the Hachyderm Mastodon server, which has over 9,500 members, decided it needed to defederate (or disconnect from) other Pixelfed servers that hadn’t been updated in order to protect their users.

It is weird to spend almost half the words in this, pretending that something in Pixelfed that wasn’t a problem on Pixelfed’s side was. This is the weirdest “vulnerability” in the world to pick if you want to pick one to hold up extensively as an example.
