CVE-2026-103988 Details
Description
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.23.0, FileRise /api/folder/renameFolder.php authorizes an authenticated, non-folder-scoped, non-administrator with a valid CSRF token against the source folder but does not independently authorize a changed destination parent. A qualifying user who owns a source folder can move that tree beneath another user's existing folder or into the root namespace, and the operation rekeys the moved ownership and ACL records to the new path. The destination must be unused and existing victim files cannot be overwritten. Distinct pre-fix errors reveal whether a specifically guessed destination path exists, but disclose no directory listing or file contents. This issue is fixed in version 3.23.0.
A vulnerability in FileRise prior to version 3.23.0 allows authenticated, non-administrator users to improperly move folders into other users' directories or to the root namespace. The issue arises in the renameFolder.php API endpoint, which fails to adequately authorize the destination folder when a folder is renamed. As a result, a user can move their folder into another user's space or to the admin-controlled root, effectively injecting files into those areas. The vulnerability is compounded by the fact that the destination must be unused, preventing overwriting of existing files, and the existence of the destination path can be inferred through distinct error responses.
Users are advised to upgrade to FileRise version 3.23.0 or later, where this vulnerability has been addressed.
