Security

node-webkit adds Node.js support and enhancement in DOM for trusted code and content. For untrusted code and content, it should remain in a normal frame or iframe, which is the same as the one in browser. So there are 2 kinds of frames in node-webkit: Node frame and normal frame.

Which frames are Node frames and which are not?

1. Local file, or remote URL matches the node-remote field. (nodejs field should not be set to false in this case)
2. Frames opened with window.open are normal frames when these flags are set: new-instance = true and nodejs = false
3. iframes has the attribute nwdisable are normal frames.

What can Node frames do?

1. Node support: access to require, global, process, Buffer and root from Node.
2. Universal access to other frames: this can get around all cross-domain security checks defined in DOM.
3. Ignore X-Frame-Options headers for child frames.

nwdisable is added in 0.5.0 rc2.
