CiviCRM includes a copy of jQuery 1.x. If a site uses jQuery 1.x or 2.x to asynchronously load third-party assets, then the third-party (or a man-in-the-middle) may trick jQuery into executing arbitrary JavaScript code (CVE-2015-9251). CiviCRM deployments should generally be safe due to low reliance on third-party assets; however, as a preventive, CiviCRM now includes the mitigation from jQuery#2432.

NOTE: If you have a customization which purposefully uses CiviCRM's copy of jQuery to asynchronously load executable JavaScript code from an external provider, then take care to revalidate it.
