Data deletion via nonce-free AJAX handlers
Published Apr 17, 2026 · Updated Apr 17, 2026
Cross-site request forgery in CMS für Motorrad Werkstätten 1.0.0 and earlier allows remote attackers to delete workshop data. Eight AJAX deletion handlers accept state-changing requests without check_ajax_referer(), wp_verify_nonce(), or current_user_can() validation. Exploitation requires a logged-in user to submit a forged request, and the impact is limited to deleting plugin-managed records or supplier catalogs.
