Missing Authorization in Storegrowth Sales Booster WordPress Plugin

Publication date: 2026-07-28

Last updated on: 2026-07-28

Assigner: Wordfence

Description
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 bogo_category_msg_create() AJAX handler, which is registered for both authenticated (wp_ajax_) and unauthenticated (wp_ajax_nopriv_) users and only validates a nonce ('ajd_protected') that is emitted publicly via wp_localize_script() on every frontend page through front_scripts() . This makes it possible for unauthenticated attackers to modify the plugin's BOGO category-message configuration stored in the spsg_bogo_general_settings option by reading the nonce from any public page and POSTing attacker-controlled data to admin-ajax.

Executive Summary

The Storegrowth Sales Booster WordPress plugin has a vulnerability in versions up to 2.1.0 where an AJAX handler lacks proper authorization checks. This allows unauthenticated users to modify plugin settings by exploiting a publicly exposed nonce.

Detection Guidance

Check WordPress sites for the Storegrowth Sales Booster plugin versions up to 2.1.0. Look for unauthorized modifications to the spsg_bogo_general_settings option via admin-ajax.php requests. Monitor for unusual POST requests to wp-admin/admin-ajax.php with the nonce 'ajd_protected'.

Impact Analysis

Attackers could change the plugin's BOGO category-message settings without authentication. This could disrupt sales promotions or misconfigure plugin behavior, potentially affecting store functionality.

Compliance Impact

This vulnerability allows unauthenticated attackers to modify plugin settings, which could lead to unauthorized changes in data handling or storage configurations. Such unauthorized modifications may violate compliance requirements under GDPR or HIPAA if they affect personal or health data processing.

Mitigation Strategies

Update the Storegrowth Sales Booster plugin to the latest version. If an update is unavailable, disable the plugin immediately. Restrict access to admin-ajax.php if possible. Review the spsg_bogo_general_settings option for unauthorized changes.
