CVE-2026-23760SmarterTools SmarterMail — anonymous administrator password reset

SmarterMail before build 9511 accepts an anonymous call to its forced password reset endpoint and checks neither the old password nor a reset token, so anyone can set a new password on a system administrator account.

YOUR NEXT MOVE

Upgrade SmarterMail to build 9511 or later now and reset every administrator password; exploit code is public, so assume the accounts were already taken.
