CVE-2025-3605

The Frontend Login and Registration Blocks plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 1.1.1. This is due to the plugin not properly validating a user's identity prior to updating their details like email via the flr_blocks_user_settings_handle_ajax_callback() function. This makes it possible for unauthenticated attackers to change arbitrary user's email addresses, including administrators, and leverage that to reset the user's password and gain access to their account.

El complemento Frontend Login and Registration Blocks para WordPress es vulnerable a la escalada de privilegios mediante el robo de cuenta en todas las versiones hasta la 1.0.7 incluida. Esto se debe a que el complemento no valida correctamente la identidad del usuario antes de actualizar sus datos, como el correo electrónico, mediante la función flr_blocks_user_settings_handle_ajax_callback(). Esto permite que atacantes no autenticados cambien las direcciones de correo electrónico de usuarios arbitrarios, incluidos los administradores, y aprovechen esta situación para restablecer la contraseña del usuario y acceder a su cuenta.
