Even if you use the relatively safe three-argument version of open, you need to sanitize the user input. Ideally, you would never use user input to open a file or pass user input to an operating system function, which is where open basically ends up at. If you open files from user input and don't use three-argument open, you get what you deserve. This is documented in I/O Operators, but maybe not in such direct words.
