Description

ApostropheCMS is an open-source content management framework. Prior to version 4.28.0, the bearer token authentication middleware in `@apostrophecms/express/index.js` (lines 386-389) contains an incorrect MongoDB query that allows incomplete login tokens — where the password was verified but TOTP/MFA requirements were NOT — to be used as fully authenticated bearer tokens. This completely bypasses multi-factor authentication for any ApostropheCMS deployment using `@apostrophecms/login-totp` or any custom `afterPasswordVerified` login requirement. Version 4.28.0 fixes the issue.
