Can loading HTML and js through ajax be considered secure?

I am currently utilizing the Jquery load function $('#result').load('test.php'); in order to dynamically load a page within another page when clicking on a tab. The page being loaded contains javascript, php, and a form. Upon inspecting the firebug console, I noticed that there is a GET request for all script sources in the loaded page. I am uncertain if this poses a security concern.

Is it possible for data to be compromised through the use of jquery load? Are there any potential issues that should be taken into consideration?

Please note: I understand that older browsers may have limitations with javascript, but are there any other aspects to keep in mind?

Answer №1

Using AJAX to load content does not pose any extra security risks.

While an attacker could potentially hijack the connection and inject malicious JavaScript (unless HTTPS is utilized), this same vulnerability exists on the page itself.

If there is an XSS vulnerability in your backend, an attacker could exploit it to execute their own JavaScript code, but they could also do this directly on the page.

Answer №2

As long as your website remains secure, sending an XHR to retrieve your own data doesn't pose any greater risk than making other types of requests.

Answer №3

The reliability factor of scripts heavily relies on the source from where they are obtained. If you have control over the scripts, there should be no concern. However, if you are sourcing them from a third party such as jQuery from Google's CDN, you are essentially putting your trust in that specific origin.
