Solo las configuraciones con un flujo de recuperaci\u00f3n se ven afectadas por esto. Cualquier persona con una cuenta de usuario en un sistema con el flujo de recuperaci\u00f3n descrito anteriormente es susceptible de que se revele la existencia de su nombre de usuario/correo electr\u00f3nico. Un atacante puede enumerar y verificar f\u00e1cilmente la existencia de usuarios utilizando el flujo de recuperaci\u00f3n, ya que se muestra un mensaje claro cuando un usuario no existe. Dependiendo de la configuraci\u00f3n, esto se puede hacer por nombre de usuario, correo electr\u00f3nico o ambos. Este problema se ha solucionado en las versiones 2023.5.6 y 2023.6.2.
