Threats affecting pkg:npm/apostrophecms/apostrophe

CVE-2026-32730 is a high-severity authentication bypass vulnerability in ApostropheCMS versions prior to 4.28.0. The flaw exists in the bearer token authentication middleware where an incorrect MongoDB query allows tokens that have passed password verification but not multi-factor authentication (MFA) to be accepted as fully authenticated. This bypasses MFA protections for any deployment using the login-totp module or custom post-password verification requirements. Exploitation requires no user interaction and can be performed remotely over the network. The vulnerability impacts confidentiality, integrity, and availability by allowing unauthorized access to protected resources. No known exploits are currently in the wild, but the issue is critical for organizations relying on ApostropheCMS with MFA enabled. Upgrading to version 4.28.
