## Technical details

This is an unrestricted file upload vulnerability in the profile picture upload handler (production/edit_picture.php). The vulnerable code directly uses the client-supplied filename without any validation of file extension, MIME type, or content, then writes it to a web-accessible directory using move_uploaded_file(). An authenticated attacker can upload a PHP payload with a .php filename extension, which is then executed by the web server when accessed via HTTP. Authentication is required as the upload endpoint is protected by the application's login mechanism. Exploitation leads to unauthenticated remote code execution with the privileges of the web server process.
