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.
