High advisory for Bricks Theme 2.4 and

Advisory overview

Bricks Theme 2.4 and before for WordPress contains an unauthenticated broken access control vulnerability in the load_popup_content REST endpoint that allows anonymous attackers to read draft and unpublished page content by supplying a popupId parameter without any status or capability checks. Attackers can obtain a public nonce via the bricks_regenerate_query_nonce action and then increment the popupId value in requests to the /wp-json/bricks/v1/load_popup_content endpoint to enumerate and disclose confidential content from any unpublished post on the site.
