CVE-2026-54414

FileRise before 3.16.0 is vulnerable to path traversal in the shared-folder upload endpoint (/api/folder/uploadToSharedFolder.php), leading to arbitrary file write and administrator account takeover. The upload filename is validated by FolderController with basename() and REGEX_FILE_NAME, which permit URL-encoded sequences (the regex blocks / and \ but not %). The raw filename is then passed to UploadModel::handleUpload, where it is reconstructed as trim(urldecode(basename($fileName))), re-intro
