Upstream source description

The WP Ultimate CSV Importer WordPress plugin before 9.2, WP Ultimate CSV Importer Pro WordPress plugin before 9.0.7 do not protect the files created by their single post export feature, writing them to a publicly accessible location under a predictable name, allowing unauthenticated attackers to download the content and custom fields of any exported post, including non-public content.
