What it does

Enforces explicit sandbox attribute for iframe elements.

The sandbox attribute enables an extra set of restrictions for the content in the iframe. Using sandbox attribute is considered a good security practice.

Examples

This rule checks all React iframe elements and verifies that there is sandbox attribute and that it's value is valid.

Failing

import React from "react";
 
function MyComponent() {
  return <iframe src="https://eslint-react.xyz" />;
  //     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  //     - Missing 'sandbox' attribute on iframe component.
}

Passing

import React from "react";
 
function MyComponent() {
  return <iframe src="https://eslint-react.xyz" sandbox="allow-popups" />;
}
