CVE-2026-13110: Wedevs Storegrowth – Upsell, Bogo, Quick View, Direct Checkout & Side Cart For Woocommerce

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

The Storegrowth Sales Booster plugin for WordPress is vulnerable to Missing Authorization in versions up to and including 2.1.0. This is due to a missing capability check on the bogo_category_msg_create() AJAX handler, which is registered for both authenticated (wp_ajax_) and unauthenticated (wp_ajax_nopriv_) users and only validates a nonce ('ajd_protected') that is emitted publicly via wp_localize_script() on every frontend page through front_scripts() . This makes it possible for unauthenticated attackers to modify the plugin's BOGO category-message configuration stored in the spsg_bogo_general_settings option by reading the nonce from any public page and POSTing attacker-controlled data to admin-ajax.
