CVE-2026-3480

The WP Blockade plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 0.9.14.

Published Apr 8, 2026 · updated Jul 24, 2026

The WP Blockade plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 0.9.14. The plugin registers an admin_post action hook 'wp-blockade-shortcode-render' that maps to the render_shortcode_preview() function. This function lacks any capability check (current_user_can()) and nonce verification, allowing any authenticated user to execute arbitrary WordPress shortcodes. The function takes a user-supplied 'shortcode' parameter from $_GET, passes it through stripslashes(), and directly executes it via do_shortcode(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute arbitrary shortcodes, which could lead to information disclosure, privilege escalation, or other impacts depending on what shortcodes are registered on the site (e.g., shortcodes from other plugins that display sensitive data, perform actions, or include files).
