Description
Concrete CMS (formerly concrete5) 9.x before 9.5.1 exposes the file usage dialog controller at /ccm/system/dialogs/file/usage/<fID> without a view permission check (CVE-2026-6826). An unauthenticated attacker can enumerate the numeric file ID space and, for every file registered in the file manager, learn where it is used: the referencing Page ID, page Version, file Handle, and the page Location (path). This discloses the site's internal page tree, unpublished and internal page paths, and file handles to anonymous callers.
This module enumerates a range of file IDs and reports the disclosed usage records. It is read-only.
