Event Booking Manager for WooCommerce 5.3.6 - 5.7.2 - Contributor+ Unpublished Event Disclosure via mpwem_load_event_list

The Event Booking Manager for WooCommerce WordPress plugin before 5.7.3 does not restrict its event listing query to events the requesting user is permitted to read, so users with contributor-level access and above can retrieve other authors' private, draft and trashed events, together with event detail the standard listing does not show them. This discloses private events and their content that WordPress withholds from users lacking the read_private_posts capability.
