Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects jquery
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.

Affected versions: < 3.4.0
