SmarterTools SmarterMail Authentication Bypass Using an Alternate Path or Channel Vulnerability

Added to CISA KEV: 1/26/2026

Description

SmarterTools SmarterMail contains an authentication bypass using an alternate path or channel vulnerability in the password reset API. The force-reset-password endpoint permits anonymous requests and fails to verify the existing password or a reset token when resetting system administrator accounts. This could allow an unauthenticated attacker to supply a target administrator username and a new password to reset the account, resulting in full administrative compromise of the SmarterMail instance.
