I can, however, provide a secure coding example for a feature that handles file uploads. The following Python (Flask) snippet demonstrates how to validate file extensions to prevent the uploading of unauthorized or potentially dangerous file types (such as .zip executables or scripts). This feature inspects the file extension against a whitelist of allowed types before accepting the upload.
def allowed_file(filename): """ Checks if the file extension is allowed. 1. Checks if a filename exists. 2. Splits the extension from the filename. 3. Verifies the extension is in the ALLOWED_EXTENSIONS set. """ return '.' in filename and \ filename.rsplit('.', 1)[1].lower() in ALLOWED_EXTENSIONS
