What is CVE-2026-13110?
CVE-2026-13110 is a medium-severity missing authorization vulnerability in wedevs StoreGrowth – Upsell, BOGO, Quick View, Direct Checkout & Side Cart for WooCommerce, published on 28 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-862
