There is confidentiality between a priest and a layman but NOT between a Rabbi and a Layman.
This actually went to the New York State Supreme court. A woman was seperated from her husband and told her rabbi she stopped going to the Mikvah. The Rabbi told the husbands rabbi and lawyer.
The woman sued the rabbi for clerical malpractice and the NY State Supreme court ruled that the rabbi was wrong for what he did, but there is no idea in judaism of confession like there is in other religions. So the woman was out of luck
