Unauthenticated Cross Site Scripting (XSS) in StoreGrowth: Smart Sales Booster for WooCommerce | BOGO, Upsells, Direct Checkout, Quick View, Side Cart <= 2.0.6 versions.

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 bogocategorymsgcreate() AJAX handler, which is registered for both authenticated (wpajax) and unauthenticated (wpajaxnopriv) users and only validates a nonce ('ajdprotected') that is emitted publicly via wplocalizescript() on every frontend page through frontscripts() . This makes it possible for unauthenticated attackers to modify the plugin's BOGO category-message configuration stored in the spsgbogogeneralsettings option by reading the nonce from any public page and POSTing attacker-controlled data to admin-ajax.

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.
