CVE-2026-92229Network attack vector

Unauthenticated shortcode execution via unvalidated current_url

Published Sep 19, 2026 · Updated Sep 19, 2026

Code injection in WPMU DEV Forminator 1.57.2 and earlier allows remote attackers to execute registered shortcodes without authentication. The quiz front-action handler passes the attacker-controlled current_url parameter to do_shortcode without validating it as a URL rather than shortcode content. A publicly reachable quiz action is required, and the resulting data access or site changes depend on the capabilities of shortcodes registered by WordPress, themes, and other plugins.
