“Security: Curl has a security model that prevents unprivileged applets from doing arbitrary things on your computer. For safety's sake, we think that most applets should be unprivileged. For commonly needed but potentially insecure operations, such as reading or writing a file, the RTE will ask the user for permission before allowing the operation. This is better than always preventing it and also better than not allowing it at all. It is of course possible to grant applets full privileges, but it's not a step to be taken lightly.”
