Detailsinfo

A vulnerability classified as critical has been found in Admidio up to 5.0.9. Affected is the function DocumentsService::renameFile of the file modules/documents-files.php of the component File Rename. The manipulation of the argument folder_uuid/file_uuid with an unknown input leads to a resource injection vulnerability. CWE is classifying the issue as CWE-99. The product receives input from an upstream component, but it does not restrict or incorrectly restricts the input before it is used as an identifier for a resource that may be outside the intended sphere of control. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Admidio is an open-source user management solution. Prior to version 5.0.10, `modules/documents-files.php` mode `file_rename_save` shares the same root-cause shape as the cross-folder move bug (`05-documents-cross-folder-move-idor.md`): the top-level rights check at lines 79-89 validates `hasUploadRight()` on the URL parameter `folder_uuid`, but the rename operation acts on `file_uuid` — a separate URL parameter — without re-checking the folder that actually contains the file. `DocumentsService::renameFile()` resolves the target file via `getFileForDownload()` (which permits view-readable files) but does not require upload right on the file's source folder. Result: a user with upload right on any folder A can rename a file in folder B as long as they can view it. They can also overwrite the file's description. Version 5.0.10 contains a fix.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-47230 since 05/19/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit.
