MEDIUM CVE-2026-15411 Deferred

StoreGrowth permits unauthenticated overwrite of sales-popup configuration

StoreGrowth through 2.1.0 registers create_popup for both authenticated and unauthenticated admin-ajax requests. create_popup() checks only the ajd_protected nonce, while front_scripts() publishes that nonce to every front-end visitor as bogo_save_url.ajd_nonce. An unauthenticated attacker can submit attacker-controlled JSON in data; popup_data reaches update_option('spsg_popup_products', ...), overwriting the saved sales-popup configuration. StoreGrowth 2.1.1 removes the unauthenticated hook and requires an admin nonce plus manage_options.

Source record

Technical description

The StoreGrowth: Smart Sales Booster for WooCommerce | BOGO, Upsells, Direct Checkout, Quick View, Side Cart plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to overwrite the spsg_popup_products option with arbitrary attacker-controlled data. The 'ajd_protected' nonce used as the sole gate is exposed to unauthenticated visitors on every frontend page through the BoGo module's wp_localize_script call, rendering it ineffective as an authorization barrier.
