Description
WPGraphQL before 2.24.2 contains an information disclosure vulnerability that allows unauthenticated attackers to determine object existence through distinct error responses. Attackers can iterate IDs against deleteMediaItem, updateMediaItem, deleteComment and updateComment mutations to discover hidden draft, private, trashed posts, custom post types, and unapproved comments.
