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

  • Disclosed: 17.04.2019
  • Updated: 11.10.2026 13:17

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.
