We are planning to release new Mastodon security updates for versions 4.4, 4.5, 4.6 and nightly this Monday, Jul 27, at around 14:00 UTC.
It solves two major security issues.
We encourage server administrators to plan for an update in the hours following the release to ensure their instance is protected. These versions will not require database migrations.
