Version 0.17.3 Our latest patch version contains several critical security fixes, including one for an authentication bypass that let unauthenticated attackers use the API as another user. It also fixes several other issues around federation, private blogs, and access control. We recommend all admins update to this version as soon as possible. This release also updates our Web Monetization support to the latest version of the standard, and includes a handful of bug fixes and improvements for users and admins.
