Authorization Bypass in StoreGrowth Smart Sales Booster for WooCommerce

Publication date: 2026-07-28

Last updated on: 2026-07-28

Assigner: Wordfence

Description
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.

Executive Summary

This WordPress plugin vulnerability allows unauthenticated attackers to bypass authorization checks and overwrite plugin settings. The flaw exists because the plugin uses a weak nonce check exposed in frontend scripts, enabling attackers to modify the spsg_popup_products option with malicious data.

Detection Guidance

This vulnerability allows unauthenticated attackers to modify WordPress plugin settings via exposed nonces. Check for unauthorized changes to the spsg_popup_products option in the WordPress database. Review server logs for unusual POST requests targeting WooCommerce or plugin endpoints.

Impact Analysis

Attackers could manipulate plugin behavior, inject malicious content, or disrupt store functionality. Since the vulnerability allows arbitrary data changes, it may lead to defacement, unauthorized product modifications, or other malicious activities affecting the WooCommerce store.

Compliance Impact

This vulnerability could lead to unauthorized data changes or exposure, potentially violating GDPR (data integrity) or HIPAA (unauthorized modifications to health-related data). Compliance risks include loss of data protection controls and potential regulatory penalties.

Mitigation Strategies

Update the StoreGrowth Smart Sales Booster plugin to the latest version beyond 2.1.0 immediately to patch the authorization bypass vulnerability.
