CVE-2026-15411: StoreGrowth: Smart Sales Booster for WooCommerce | BOGO, Upsells, Direct Checkout, Quick View, Side Cart <= 2.1.0 - Missing Authorization to Unauthenticated Options Update via create_popup AJAX Action
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 spsgpopupproducts option with arbitrary attacker-controlled data. The 'ajdprotected' nonce used as the sole gate is exposed to unauthenticated visitors on every frontend page through the BoGo module's wplocalizescript call, rendering it ineffective as an authorization barrier.

Because the vulnerability is an authorization bypass allowing unauthenticated attackers to overwrite the wp_localize_script gate (ajd_protected nonce) and the spsg_popup_products option, restrict access to the storefront/pages serving the plugin’s frontend script so unauthenticated visitors cannot reach the affected AJAX action unless properly authenticated/authorized.
