As a result, an authenticated user holding the block-add scope could store, and cause the page to render, a reference to a file that the file-manager authorization policy would otherwise reject, disclosing that file&#8217;s URL and preview to the editor and to visitors of the affected page. Under public file storage, the URL and thumbnail are exposed directly; under private storage, the disclosure is limited by the permission-checked download URL.\u00a0The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.1 with vector CVSS:4.0\/AV:N\/AC:L\/AT:N\/PR:H\/UI:N\/VC:N\/VI:L\/VA:L\/SC:N\/SI:N\/SA:N.
