Do both parents have to be cystic fibrosis carriers for a child to get it?

In brief: Yes

Cystic fibrosis is an autosomal recessive disease which means that a person needs to inherit 2 abnormal genes in order to have the disease.
Those 2 abnormal copies come one each from the 2 parents, so both parents need to be at least carriers.
