CVE-2026-13110: StoreGrowth: Smart Sales Booster for WooCommerce | BOGO, Upsells, Direct Checkout, Quick View, Side Cart <= 2.1.0 - Missing Authorization to Unauthenticated Arbitrary Plugin Settings Modification via bogo_category_msg_create AJAX Action

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.
