CVE-2024-37458Network attack vector

Admin-notice dismissal via missing nonce validation

Published Jan 2, 2025 · Updated Apr 28, 2026

Cross-site request forgery in Extend Themes Highlight 1.0.29 and earlier allows remote attackers to dismiss WordPress admin notices. The highlight_admin_ajax_welcome_notice_dismiss() function accepts the notice-dismissal request without valid nonce verification. Exploitation requires a site administrator to follow a crafted link or perform a similar attacker-induced action; the bounded consequence is dismissal of dashboard notices.
