Cross-Site Scripting in jquery
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.
