Technical details

The StoreGrowth plugin for WordPress (versions up to 2.1.0) fails to implement proper authorization checks on its AJAX actions. While the plugin uses an 'ajd_protected' nonce for security, this nonce is leaked to unauthenticated visitors on every frontend page via the BoGo module's wp_localize_script call. Consequently, an unauthenticated attacker can use this leaked nonce to bypass the intended security gate and overwrite the 'spsg_popup_products' database option with arbitrary data. This is classified as a Missing Authorization (CWE-862) vulnerability.
