The application leaks the password reset token within a hidden HTML input field on the password reset page. This allows any unauthenticated attacker to retrieve the reset token for any user by simply querying the user\u0027s email, leading to full Account Takeover (ATO) without requiring access to the victim\u0027s email inbox. This vulnerability is fixed in 1.6.3."

La aplicaci\u00f3n filtra el token de restablecimiento de contrase\u00f1a dentro de un campo de entrada HTML oculto en la p\u00e1gina de restablecimiento de contrase\u00f1a. Esto permite a cualquier atacante no autenticado recuperar el token de restablecimiento para cualquier usuario simplemente consultando el correo electr\u00f3nico del usuario, lo que lleva a una toma de control total de la cuenta (ATO) sin requerir acceso a la bandeja de entrada de correo electr\u00f3nico de la v\u00edctima. Esta vulnerabilidad est\u00e1 corregida en 1.6.3."
