CVE-2026-32730ApostropheCMS MFA/TOTP Bypass via Incorrect MongoDB Query in Bearer Token Middleware
High 8.1
In plain English
A high-severity improper authentication in apostrophe from apostrophecms. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 33% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official 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.
