Versions of `jquery` prior to 1.9.0 are vulnerable to Cross-Site Scripting. The load method fails to recognize and remove `<script>` HTML tags that contain a whitespace character, i.e: `</script >`, which results in the enclosed script logic to be executed. This allows attackers to execute arbitrary JavaScript in a victim's browser. ## Recommendation Upgrade to version 1.9.0 or later.
