A vulnerability allowing unrestricted file uploads has been identified in FastApiAdmin versions through 2.2.0. This issue resides in the Scheduled Task API, specifically within the user_avatar_upload_controller function of the file /backend/app/api/v1/module_system/user/controller.py. The vulnerability arises because the file upload mechanism trusts the Content-Type header to determine allowed file extensions, without proper validation or normalization of file paths. As a result, authenticated attackers can exploit this flaw to upload arbitrary files to the server. When this vulnerability is combined with the scheduled task APIs, it can lead to remote code execution.
