Vulnerability in admidio/admidio (CVE-2026-47231)
Summary
Vulnerability in admidio/admidio (CVE-2026-47231). Confidential information can be exposed externally. Exploitable via GET /modules/documents-files.php. Mitigation: upgrade to 5.0.10 or later.
Original description
The description as published by the source.
Summary
modules/documents-files.php gates state-changing modes by checking that the actor has hasUploadRight() on the URL parameter folder_uuid. The move_save handler then operates on a separate URL parameter file_uuid and calls File::moveToFolder($destFolderUUID). File::moveToFolder() checks the upload right on the destination folder but never on the source folder containing the file. As a result, any user who can upload to any single folder can move any file from any other folder — including private folders to which they have no view rights — into a folder they control, and then download it. Confidentiality is broken (private file contents leak) and integrity is broken (the file is removed from the original location).
Details
Vulnerable Code
modules/documents-files.php:79-89 — top-level rights check binds to URL folder_uuid:
if ($getMode != 'list' && $getMode != 'download') {
// check the rights of the current folder
// user must be administrator or must have the right to upload files
$folder = new Folder($gDb);
$folder->getFolderForDownload($getFolderUUID);
if (!$folder->hasUploadRight()) {
$gMessage->show($gL10n->get('SYS_NO_RIGHTS'));
// => EXIT
}
}
modules/documents-files.php:187-204 — the move_save branch loads the file by UUID without revalidating the file's actual parent folder:
case 'move_save':
$documentsFilesMoveForm = $gCurrentSession->getFormObject($_P…
