Unauthenticated shortcode execution via unguarded AJAX action
Published Nov 22, 2023 · Updated Apr 8, 2026
Missing authorization in DeluxeThemes UserPro 5.1.4 and earlier allows remote attackers to execute arbitrary WordPress shortcodes via AJAX. The userpro_shortcode_template handler registers a nopriv AJAX action and passes the request's shortcode value to do_shortcode without a capability check. No account is required; the direct impact depends on available shortcodes, including sensitive-data disclosure when the separate shortcode disclosure flaw is present.
