HighCVSS 7.2
Published: Updated: Translated: NVD NIST

Summary

The StoreGrowth plugin for WordPress up to version 2.1.0 is vulnerable to stored XSS via the 'message_popup' parameter. Insufficient input sanitization and output escaping allow unauthenticated attackers to inject arbitrary scripts that execute when a user accesses an injected page. The 'ajd_protected' nonce is exposed to all visitors.

Risk Assessment

An unauthenticated attacker can inject malicious scripts that execute in users' browsers, leading to session theft, redirects, or other harmful actions.

Recommendation

Update the StoreGrowth plugin to the latest version that includes security fixes.

Original NVD description (English source)

The StoreGrowth: Smart Sales Booster for WooCommerce | BOGO, Upsells, Direct Checkout, Quick View, Side Cart plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'message_popup' parameter in all versions up to, and including, 2.1.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit is possible because the 'ajd_protected' nonce required by the create_popup handler is exposed to all unauthenticated frontend visitors via wp_localize_script under bogo_save_url.ajd_nonce, effectively bypassing the nonce-only access control.
