      "value": "The password change endpoint in Open Source Point of Sale 3.4.1 allows users to set their account password to an empty string due to missing server-side validation. When an authenticated user omits or leaves the `password` and `repeat_password` parameters empty in the password change request, the backend still returns a successful response and sets the password to an empty string. This effectively disables authentication and may allow unauthorized access to user or administrative accounts."

      "value": "El endpoint de cambio de contraseña en Open Source Point of Sale 3.4.1 permite a los usuarios establecer la contraseña de su cuenta como una cadena vacía debido a la falta de validación del lado del servidor. Cuando un usuario autenticado omite o deja los parámetros ’password’ y ’repeat_password’ vacíos en la solicitud de cambio de contraseña, el backend aún devuelve una respuesta exitosa y establece la contraseña como una cadena vacía. Esto deshabilita efectivamente la autenticación y puede permitir el acceso no autorizado a cuentas de usuario o administrativas."
