CVE-2024-13453Network attack vector

Unauthenticated shortcode execution via unvalidated block attributes

Published Jan 30, 2025 · Updated Apr 8, 2026

Code injection in WPForms Pirate Forms 2.6.0 and earlier allows remote attackers to execute arbitrary shortcodes without authentication. The Gutenberg block render callback passes an attacker-controlled shortcode attribute to do_shortcode without restricting it to the Pirate Forms shortcode. Reachability requires the server-side block-rendering route, and consequences depend on the shortcodes registered by the WordPress site.
