CVE-2026-23760CRITICAL 9.8

SmarterTools SmarterMail versions prior to build 9511 contain an authentication bypass 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. An unauthenticated attacker can supply a target administrator username and a new password to reset the account, resulting in full administrative compromise of the SmarterMail instance. NOTE: SmarterMail system administrator privileges grant the ability to execute operating system commands via built-in management functionality, effectively providing administrative (SYSTEM or root) access on the underlying host.

CVE-2025-10484CRITICAL 9.8

The Registration & Login with Mobile Phone Number for WooCommerce plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.3.1. This is due to the plugin not properly verifying a users identity prior to authenticating them via the fma_lwp_set_session_php_fun() function. This makes it possible for unauthenticated attackers to authenticate as any user on the site, including administrators, without a valid password.
