NVD Description

Note: Versions mentioned in the description apply only to the upstream jquery package and not the jquery package as distributed by Ubuntu.

jQuery before 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.
