I do not believe that it is permissible to have a Mass at the marriage ceremony between a baptized Catholic and a unbaptized person.

Not permissable at a marriage between a baptized Catholic and a baptized non-Catholic, either.

Because of problems concerning Eucharistic sharing which may arise from the presence of non-Catholic witnesses and guests, a mixed marriage celebrated according to the Catholic form ordinarily takes place outside the Eucharistic liturgy. For a just cause, however, the diocesan Bishop may permit the celebration of the Eucharist.
