We recommend every instance administrator to update as soon as possible.
If you are using our nightly releases, a container image with the fix has been published with the `nightly.2025-02-28-security` tag.

If you are running Mastodon 4.2: Mastodon 4.2.17 drops support for Ruby 3.0 (which is no longer supported upstream). If you are using Ruby 3.0, you can update to Mastodon 4.2.16 which contains the latest security fixes, but please note that this version has a known vulnerability if you are using SAML authentication with Mastodon. If you are running Mastodon 4.2 + Ruby 3.0, we strongly encourage you to update to Ruby 3.2 and Mastodon 4.2.17 or above. #mastoadmin
