Exhibition catalogues seldom have an identifiable author. Instead, the title is used to identify the catalogue in a reference list.
The publisher will be the organisation who created the catalogue: the festival, professional body, or gallery. The place of publication is the location of the premises of the organisation who created the catalogue.
The artist is responsible for the artworks, but usually not for creating the catalogue. For this reason, the artist in not named specifically in the reference, unless they happen to have their name in the exhibition title.
