Descriptions

When duplicating a BigBlueButton activity, the original meeting ID was also duplicated instead of using a new ID for the new activity. This could provide unintended access to the original meeting.

Al duplicar una actividad de BigBlueButton, el ID de la reunión original también se duplicó en lugar de utilizar un nuevo ID para la nueva actividad. Esto podría proporcionar un acceso no deseado a la reunión original.
