jQuery Cross Site Scripting vulnerability

Cross Site Scripting vulnerability in jQuery v.2.2.0 until v.3.5.0 allows a remote attacker to execute arbitrary code via the <options> element.

XSS in jQuery as used in Drupal, Backdrop CMS, and other products

jQuery from 1.1.4 until 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true, {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable __proto__ property, it could extend the native Object.prototype.

Potential XSS vulnerability in jQuery

Impact

Passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.

Patches

This problem is patched in jQuery 3.5.0.

Workarounds

To workaround the issue without upgrading, adding the following to your code:

jQuery.htmlPrefilter = function( html ) {
    return html;
};

You need to use at least jQuery 1.12/2.2 or newer to be able to apply this workaround.
