CVE-2026-47226 - Admidio: Authorization bypass in file_delete enables cross-folder file removal by authenticated users without delete privileges

CVE ID : CVE-2026-47226 Published : Aug. 12, 2026, 12:51 p. m. • 13 minutes ago Description : Admidio is an open-source user management solution. Prior to version 5. 0. 10, an authenticated Admidio member with upload rights on any one folder can permanently delete files from folders where they have only view access. The authorization check at the top of `modules/documents-files. php` evaluates upload rights against the attacker-supplied `folder_uuid` URL parameter — not the file's actual parent folder. The `file_delete` handler then only verifies view rights on the file's real location, never upload rights. By passing a folder they legitimately own in `folder_uuid` while targeting a file in a restricted folder via `file_uuid`, an attacker bypasses the upload-right check entirely and permanently deletes the file.
