🚨 Upgrade or be hacked. 🚨

There is a "hacker" group (script kiddies) targeting Mastodon sites that are not yet running Mastodon 4.5.10.

Version 4.5.10 fixes several security vulnerabilities that are relatively easy to exploit and were discovered in earlier versions of Mastodon.

If you're not running 4.5.10 (or newer), you are at risk. ⚠️

If you're using a nightly build of Mastodon, make sure you're running one that was released after the release date of 4.5.10. And yes, I said release date, not version number — earlier 4.6 nightly builds do not include the security patch. ⚠️

If you're delaying the update because you're running a modified version of Mastodon, consider whether maintaining those modifications is worth the security risk. ⚠️
